I asked for 12, I thought there may be some interest from others.

Nice looking work, I like the toys in the background better!

I poked the bear when I started the original color discussion. After some debate at home, we decided to go with something different. The gray and blue as the same shade as the stripes on the interior.

I am waiting for a valve cover spacer to show up so I can get the covers and the risers on. The roller rockers are a little too tall for the original valve covers. I was going to get new valve cover but I saw a Few threads on here about some of the tall covers interfering with the manifolds. Plus I had my covers powder coated to match the pulleys.

I didn’t keep it original, but I think it will look good.

My thoughts exactly

Great looking project Steve - you'll be on the water in no time

Just purchased this 77 from a Neighbor of mine , boat has been sitting under shelter for last 7-years. Was hoping someone could help identify which engine I might have. Distributor is mounted about flush with intake .

Very difficult to post from a phone on this site. Here below are the differences between a 302 and a 351 - just measure across the intake bolts . Approx 7 1/4 is a 302. 9 1/4 is a 351

I got my Ski Tique in the water this weekend for a very quick ride from the launch to the boat hoist before I got rained on. I didn’t get a ton of time to really try it out and run through some rpm and speed ranges.

I can say the difference in power and hole shot is amazing.

I kept an eye on the temp and oil pressure on my short drive home. Oil pressure was great but the temp was running high. Prior to the rebuild the engine ran about 160-165 deg. It ran at about 190 at idle then dropped to 180 at about 2000 rpm. The temp gage is new, so I swapped the old one and still saw the same temp.

I rebuilt the raw water pump with a new kit. The circulating pump is new from SkiDim, all hoses are new, hose clamps are tight, transcooler is clean and free of debris, 143 deg t-stat installed, manifolds and risers are about 5 years old. I am getting good water flow out of the exhaust, but noticing steam too.   I was able to hold my hand on the heads and manifolds after I ran it for about 20 minutes yesterday.

I also added an acme 1210 prop, which apparently makes a disturbing noise upon decel.

Is it possible that this is my new operating temp? Does a tighter more powerful engine run hotter?

I initially ran the engine with a garden hose and a Timmy T. Temps were the same according to an IR thermometer.

Below are a few videos of it running on the hose.

I felt better once I read on here that the ACME 1210 made that noise, it was quite different than what I am used to hearing.

I aimed the IR at the heads, Ill check again this evening at the temp sensor.

The ground should be good, no tape or putty on the threads. There was a plug in the hole when I painted the engine, so I know the threads are free of paint.

I may change the impeller again,, I primed the pump when I ran the engine on the hose, but thought maybe it got damaged while trying to get the engine to start for the first time.

I just ordered myself the acme 1210. Don't have prop yet, looking forward to it's arrival and seeing the increased performance.

Wondering if you still have that prop noise on deceleration? Any thoughts after using it for a year?

Just trying to adjust my expectations.

Thanks!
