Out celebrating my birthday with the family and of course this is when it happens.
Filling ballasts, wishing I had started the plumbing project of ballast system (next project). Boat came by and wave pushed up to edge of delta shore. When I stated and powered away from the shore, stated to note some squeaking of the belt. Most of the time it clears but by the time I had moved to a safe point off the shore, the squeaking stopped and the engine temp went up with alarm and I shut it all down. Smelling burning rubber, open engine compartment and sure enough the belt snapped. Examining belt, it literally melted at a point.
All pulleys spun, water pump was firm but differently would spin. Since I had a backup belt, installed it. Checked the intake under the boat, thinking maybe sucked up something when pushed into the shallow area, but it was clear. I restarted engine with continued overheating and some squeaking of the belt. Moved to do an impeller replacement on the water.
Thanks for all past recommendation on this site to have backup impeller and belt on the boat.
On re-evauating the pulley on the water pump had like a melted rubber from the previous belt that broke. I thought for sure this must be the problem. I removed impeller, first time to do it on the water. A little scary to have water flowing into the boat from the intake line, but easily raised it about the water line and controlled. With free flowing water, it did no appear to be any problem with intake side., Impeller did not appear bad.

After install of new impeller, drove it for about 2-3 minutes and noted the water temp heading above 200 and shut it all down. Was able to find someone to tow us in.
Searched this forum and took suggestions on tracking intake. When I did, I realized my boat does not have any filter or strainer for my intake line. Can anyone tell me if I should install one? I was reading on V-Drive documentation of seasonal cleaning of cooling chamber. I removed that and nothing there that would be restricting intake.

Now I am not sure where to go. My understanding is if it was the thermostat, it usually fails open.
Could it be the water pump? How do you evaluation it?
Any suggestions on where I can go form here. Going to hardware store to build a connection for garden hose to intake to continue the problem solving.
