He stated bees formed a nest as it had sat for 2 yrsFirst two things that come to mind are there is something caught up in the impeller to keep it from turning and the other is there is something clogging the hole where the water comes out. The fixes are to look for debris in the pump through the clean out port or under the boat where the intake grate is and run weed eater line down the hole to try to unclog it. Having been around this stuff for years and see water not coming out from time to time, I wouldn’t be alarmed just yet. Probably an easy fix. Keep us posted and I bet this group can help you figure it out.
Thank you for responding he said water is now flowing and believed after poking around what he believed to be a wasp built or clogged it up.but I noticed you said that water not spitting out wouldnt cause it to overheat ? It is a fresh water boat and supposedly the water is flowing and if it doesn't over heat now I was going to buy it but not sure how to giage if there is still a issue?Did you buy the boat yet ?
since you have a 24 yr old 2 stroke..... ( edited, sorry I didn't read you were looking at a 2004 )
since it's overheating I would guess you're not getting water through the engine,
water comes in at at the jet nozzle, if you're impellers aren't pushing good water ( they're dinged up, you've got trash in the pump area) it can't go through the inlet screen with enough force to push it through the engine,
as brad commented above, after 24 yr the cooling passages could be clogged up, on the engine or the exhaust,
the holes on the side of the boat or just tell tales, if the line from the engine to side of the boat is clogged it doesn't affect engine cooling at all,
if you just have impeller or screen inlet problems, that's an easy fix,
if you have clogged internals, I'd pass unless you just have time and money to burn,
