Prop Size, RPMs, & overheating

[jongolds]

The prop will get about 5800 rpm. I was hitting a wall at 5k because that's when the computer would start dropping RPMS due to the over heating problem. From a cold start I was able to get them up higher.

I've changed the thermostats & poppet valve (still not sure what this does). Haven't done the pump/impeller yet but it's looking like that's gonna be next. There's not much more I can do while it's in the water and I can't get it out until high tide late Sunday afternoon.

Right now I'm selling the bunk trailer that I have for it to get something with brakes on both axles. Considering that I don't trailer much, and that everyone says the bunks are better for the hulls, I was planning to stick with the bunks but I'm not sure now. In the event something happens and I need to get it out of the water on short notice, I don't want to be worrying about the tide.
