I was very concerned at the heat of mine. We backflushed it with a garden hose as you mentioned then forced water up from the foot to make sure it was flowing well. Mine got quite warm but didn’t stick. No tight spots turning it over and once it cooled off it fired first pull again.
I had issues getting my main jet to seat properly then we had to adjust the float (I’d have to check but it’s right around 1” maybe an 1/8 below). We had also shimmed my motor up an 1/8th so it was a bad combo for cooling. Usually if I’m anywhere but full speed I get a good flow of water out.

That looks like a great spot to test
Unfortunate events with your 80. Does coolant throw a nice stream out the top of block tell tail hose after you start up and get going before getting on plane at higher revs? If not a steady solid stream under this state there is still restriction in the passage. If that is the case I have had luck back flushing with house pressure garden hose thru the top tell tail hose fitting and removing the tower brass plug. If still not totally clear I have had to remove the power head and the cylinder head and dig deeper to find the restriction. Is the float adjusted to the correct dimension?
These engines do not like overheating. -
Well I had a pretty humbling weekend. We had everything from a boat going under on Saturday (luckily only in 2-3 feet of water and motor was already shut off) to potential motor damage yesterday when a motor inhaled a piece of seaweed. While all this was going on with other boats I was struggling big time with carb issues. Ultimately we did get my carb mostly sorted and on my final test run I also got my coolant passages plugged with seaweed (won't be running at that low tide again). Fortunately I was watching and brought the boat in on lap two (was in and out of the throttle not full speed laps). My 80 got very hot but after cooling down and flushing the coolant passages it started fine and seems to be alright. Unfortunately I think Carruthers has some work to do on his.
Overall the win of the weekend was seeing my brother get more comfortable in his new red boat. He was making huge strides and getting faster every run out! His newly acquired 80 runs well and the boat seems quick and stable.22C6AF64-89E0-4C30-8679-108B6BCD852F.jpeg -
My brother is certainly showing himself to be the smarter of the Albert’s. He bought a boat that only needs minor paint work, and a motor that wasn’t pre-blown up. Sometimes I wonder if we’re even related. -
Lots going on with work this spring but looking to get out next Thursday (Canada Day), just making a few minor adjustments (fin height and carb changes). I figure another dozen laps and the motor should be broken in enough to start seeing what it can do.
We're picking up another 20ssh for my brother later this week, may have it gone through by next week as well. It's exciting times in the Maritimes up here in New Brunswick.

Congratulations it is really great that you did this looks really good and appropriate safety gear. Now its just run and fun time with some tweaks along the way. What height did you set the engine, kicked in, level or out and what do you have the timing full advance set at?Leave a comment:

0DA0F784-0120-4F12-9236-942FF8138835.jpeg So I guess the question is how did it work? The short answer is that it works great. Only 2 minor glitches all day, lost my fuel cap and once had the motor cut out when I may or may not have shifted to much to look back at the black bezoat (definite moment on dread followed by great relief).
We didn't bother with GPS or recording laptimes, the water was only good enough to go full throttle for part of the straightaways. Instead I focused on breaking in my engine with pretty gentle laps and only the occasional short bursts of WOT to see how it was going to fly.
My sincere thanks to all those who made this happen. This is a big milestone in the life of the project but really its just the beginning of a new racing life for this great little boat.

Ok, so sending the black boat out first was a bit of a cop out. So Now it was time to step into the water (by this point it was almost a bomby 60 degrees out ). But did I mention how people feel about quitters?
Here we go, it floats...time to get started.
