Back to the Island

Catastrophic Engine Failure!

After a short tow from Paramount's berth around to Granville Island, the boys get her ready for the engines to go back to the shop for forensic analysis to determine where the failure occurred. 

Was it just the wrong sized pistons with their 11-1 compression ratio? Or was it something else that started the heat that started the meltdown?

The Granville Island Boat Yard guys stayed back after hours to do a quick lift. A two hour quick lift! The engines were out in a flash - Gord the crane wizard, and all the crew were keen to catch the Canucks playoff game.

Comment From Paul, Founder of The Chris Craft Commander Forum


The Internet is a small world...


Paul has commented on this blog site - he must have found it on his own. We had been waiting to write to his website after everything was finished on Miss P. 

He has beat us to it, and comments on our engine problems. He is THE MAN - when it comes to Chris Craft Commanders, he is the founder of the CCC Forum, an architect by trade, a Chris fanatic by admission. We are grateful for his website and value his comments on our situation immensely. This is what he has written:

"Man I am soooo sad to hear news like this, especially after you have put your heart and soul into the restoration. I note the use of Keith Black pistons, many people have used these as a basis for custom 427 pistons with good results.


The only things I can imagine that would cause the motor to heat up like that would be poor ignition/fuel mix, a very poor automotive timing setting (and not following the dimple on the flywheel at 500-RPM while in gear for the marine Chris Craft setting), or a leaned out fuel mix (or both simultaneously), or perhaps an impeller that went out causing a catastrophic over-heating of the motor while running at speed. 

Forensic review of the impeller and strainer, and coolant would give an indication of their integrity. 

This could have been caused by advanced ignition timing, wrong plugs, lean fuel, intake manifold vacuum leak, sticking valves (perhaps incorrectly set for a solid lifter motor), insufficient cooling, poor lubrication. 

I have considerable resources I can share with you if you need them on the 427 marine motor. Drop me a line at ChrisCraftCommander@hotmail.com
and I'll do whatever I can to assist.

Sincerely,

Paul

Melt Down!


The Keith Black Pistons Blow Apart

The engine has been stripped down in the boat. The damage is extensive - all eight pistons have blown apart or are on their way. The aluminum got so hot it vaporized - large pieces of the pistons are missing.





We are investigating the cause. The timing was checked twice. The carb was rebuilt. They performed perfectly in the dyno test.

Oil samples from the other engine are being analyzed and we should know this morning if the port engine has done the same thing. With all eight affected in the starboard the port will need to come out as well. 







It was a very sad day for everyone involved in the restoration - she was running beautifully before the meld down. She was clipping along at 19 knots. 


Dr Doug has jumped in to help rescue the disaster. He's been in the bilges helping G get to the bottom of the engine and wasting no time to resolve this for Captain Doug who is pictured here running the good doctor, with his wheel barrel and tools, back to Granville Island.

It was time to cry in the beer.

"I still don't want bowling shoes ..."

Despite the most major of set-backs on the first sea trial for Paramount - Captain Doug isn't willing to trade in the deck shoes.

After months of labour & tons of TLC everything is restored to as new - all systems have been upgraded, the engines bench tested - Miss P is a looking and feeling like a new boat and she's ready to go for a first burn.

  

Everything was going beautifully for the first 1/2 hour at RPMS below 3000. Paramount was up and out of the hole at 2800 making 9 knots in a 4 knot tide on the bow. On a slack or slower tide she should be out of the hole sooner and a knot or two quicker.


Below is the view from the bow at around 3000 RPM running around 14 knots, into the tide. Paramount is up and sitting pretty. She's hasn't run this well for Doug, she's feeling sporty at the wheel, a slight correction and she is on her new heading with no delay.






A fine moment - the Captain at the wheel, feeling the difference in power and response. His beautiful boat is running like new.

A Pair of Kittens


After so many hours spent researching, emailing, tracking down parts, cleaning, prepping and rebuilding at considerable expense, the two original 427 engines are truly better than new







They are back in Paramount and ready for the final helm wiring to be run. They were dyno tested at 340 HP and with the original exhaust manifolds and cooling system they should be good for 30-40 HP more.


It is Friday night and Dr Doug has had a long week. As he searches his pockets looking for his trusty Swis Army knife which he has forgotten he has used in place of the machinists standard clothes peg to keep the choke open. Can he find it? Of course he can! At the end of the video Doug's hand gesture says it all...finished, a job well done!

Getting there - one day at a time...


The months have flown by since her restoration project started. Dr Doug has been holed up in Paramount for the past two months working on the last major upgrade to be done - the wiring. 

The new and very subtle "lizard skin" wallpaper is up, the headliner looks beautiful, the brightwork is looking bright and the million pieces of the puzzle are now returned to their correct place. The mast is standing and the chrome looks stunning.

 A red night light has been added to the helm, great underway and a nice touch at the dock entertaining.

.

Dr Doug has rewired the old gal, the engine room now glows with 12V lights, no need for trouble lights now! The house bank of 6 gel batteries will keep the music playing all night long.


The area that was used for the main panel is now used as the relay area bringing the vast number of wires into one neat and accessible junction - with the new panel moved over to the small cupboard. All of the electronics are routed to the one place, stereo, battery switches and breaker panel.


Bring on the roar, or is that a purr?


The engines are ready to go! Here Doug tightens up the sea strainer. A new nylon washer will stop the drip. We are opening the sea cocks to start the engines in the boat for the first time.

Closer to Splash!


The dust has settled and Miss P is starting to look like her "old-self". With fresh varnish in the helm, and new everything; engines, headliner, wallpaper, wood flooring, curtains and shag carpets through-out, she's looking as good as the day she was first launched, 41 years ago. 



The flooring has allowed the hatches (pictured here before they are covered) to be accessed at any time. Shag throw rugs are being used to cover the main engine hatches, and in the aft cabin, which have been trimmed in the dark oak.


The new headliner has been made in sections of removable panels, there will be thin strips of white wood installed to keep them in position. Like the carpets, wall to wall stretched fabric stapled up made it impossible to gain access anywhere. With the new panels, each section can be dropped down in minutes, exposing wiring runs and allowing thru-deck fittings to be re-sealed, and electronics replaced in the years to come.



G the machinist from Pacific Parts who rebuilt the engines has been busy in the bilges on the weekends doing the cooling side and helping align the engines to the shafts. I joked with him this morning that they are his engines, in Doug's boat. 

He's agreed to be the motor man for Miss P ongoing. He will grow old looking after our gal. The original engines ran for 40 years! With the re-builder being responsible for future servicing and the installation of a fresh water flush kit these should go for 50 more!


The upholstery is back from Jott Industries and they have done a cracker of a job! Adding a small head-roll to the bench and some automotive style piping to the helm seats. The automotive styling we borrowed was not from a car, instead it was taken from the 1968 19' Commander's seats - undoubtedly influenced at the time by Detroit.



Props On! and Off!

Everything was going great, until the resident prop polisher and boatyard's old salt - Don - discovered that they were not a matched set. The prop shop had not polished the barrel of the prop and had used a grinder to clean the blades. Don massages the props with emery paper and doesn't loose a gram of the bronze. Using a grinder to polish a prop he thinks is murder and should be a capital offense. Not to clean the body of the prop - "what kind of prop shop does that!" demands the now cranky Don.

After doing the first, he moved to the second and within minutes he was in a flap - the props don't match! I heard shouted from the stern. When he sanded down the second barrel it was confirmed the two props were a mismatch and somewhere along the line Paramount's two sets of props were mixed-up and one from each pair were on the boat.

If Don didn't give the props the extra care, we would have missed this. In fact we had. They were back on Paramount.

We could have spent the next year trying to figure out what and where the difference was - she might have pulled to one side, she might have vibrated on one side - and we would have checked everything, transmissions, compression and still scratched our heads!



Using the latest $4000. laser tool for aligning the shafts was a solution that ensured true alignment for the very first time for Miss P. 

Dr. Doug discovered the engine stringers were too high and everything after that had been forced - right down the shaft. It was almost impossible to turn the props by hand. Doug took 1/2" off the top off the stringers to allow the engine to sit lower and be adjusted up or down.

With the laser in the shaft-log pointed back, the struts could all be shimmed and aligned dead centre. Tissue paper was stretched over the strut covering the cutlass bearing, the laser was then shot through allowing for an exact centre right the way back through the three struts. It was then shot at the engine and the dead-centre of the coupler was found and the engine mounts moved to facilitate the feeler gauge checking for the correct and perfect alignment.

We should be getting some strong winds in the next few days. I'm hoping to see these props turning in the wind.
