I guess I will just make this an update thread until I get it in the water. I did redo the dash and put all new SW gauges and had the bezels, throttle plates and a few other things powder coated including the battery hold downs. Unfortunately in getting the boat powered up I was able to tilt the outdrive and I have a leaking fitting which I think will require a whole new hose. Looks like a real pain in the butt to change too.



I also got a new oil cooler and PS cooler combo with a thermostat that was suggested and is sized to my motor and HP.

Of course with a new build you would expect a few small issues. So the engine sounds good through exhaust but the valves are really loud. So after a fiasco on the dyno with one of the lifters having a plunger stuck sideways somehow and the shop not being able to adjust them for some reason. I was able to swap them out (lifters are Howard 91163 - supposed to be Morel?) while they had it on the dyno with a new set and were able to complete with good results. After the engine sat for about 5 weeks, I was able to start it. Unfortunately the valves were super noisey but it has 50 lbs at idle and I using a melling 10771 pump. I ended up having to remove the exhaust and found all but 2 rocker arms were loose. I ended up readjusting with 1/4 as I have read a lot of opinions on the adjustment for these as they are just below a race lifter. Well it still ticked and rattled.
I emailed Howards and they said

"Lash should be turn. That lifter will make some noise during normal operation. Also keep in mind you are getting noise from the rockers & tie bars on lifters."
"Typically lifter manufacturers do not recommend oil heavier than 10W-40 for proper operation."

I am going to re-lash the valves and run the boat with my Lucas 20w-50 Break-In oil as I have about 18 quarts to change out. Will change it after hopefully a good full day of boating.


I also bought a new carb off a member here as it was dyno'd with a 850 demon and going to try this 1000cfm Pro Systems.

Well it is finally done except for a stereo and some kick panels. Seeing the engine hatch open for the first time was quite an experience. Very happy with how it turned out and I sure did learn a lot of some very nice and knowledgeable people on this site. We are hopefully going to take it out on its first trial run today or tomorrow.

We had our maiden voyage at Donner Lake and everything worked great. Need to do a little carb adjustment and I think I need another prop. Here is a little video
