1990 Yamaha 3.0 L4

Won't pump water on the muffs. Can't figure out why.

LOL

On a serious note, I just bought this boat and will be doing some maintenance this winter along with getting the transom rebuilt and redoing some of the interior. Should be tons of fun.

Did you find all the pieces? They will plug things up and cause overheats if not found.

I ran water through the hose that runs from the raw water pump to the engine water pump into the engine. I did this so that I knew the block/manifold wasn't cracked before purchasing. Seemed to flow fine. There was a lot of debris that fell out of that hose as well as what was jammed up into the raw water pump. I will pull the thermostat and replace that before I put it out on the water this Spring so I will look around in there for pieces. Anywhere else I should look?

Can tell that is a freshwater boat. Steel trailers wouldn't look that nice if it had ever been dipped in salt water.

Yup, a low hour boat too from what we can tell.

What is that hose going to on the front of the drive just above the trim ram? Not a Yamaha item.
