The engine and outdrive are Mercruiser. You wouldn't need a Maxum Parts list. You would need a Mercruiser service manual for the size and year Mercruiser engine installed. Any mercruiser dealer or dealer of Brunswick boats can order mercruiser parts (Bayliner, Searay, etc).

The high temp alarm going off at 200 is normal. Water boils at 212 F.

Start with the impellor, then look at manifolds and risers.

MMWJR,
Just replaced it tonight. Not a hard job. Only special tool I needed was the gear lube pump as to not set the lower end up to cavitate. Only problem was (as suspected) is that the old impeller looked brand spankin new. But I did find a lot of rust chunks throughout my disassembly, which most definitely points to manifolds and riser time. Yay. Just what I wanted to do one month after buying a boat. Guess thats the name of the used game huh?

Shrew,
Maybe I didn't articulate clearly that I was also looking for a parts breakdown for the boat itself. I would like to see an illustrated parts breakdown of my boat. This would really help in the future for hardware and other things that I may want to find. I figure part numbers will help in my search to find or cross-reference discontinued maxum parts.

Could also be a bad t-stat.

Kind of shot gunning this, I would get a handheld IR temp sensor to check temps and what is hotter than it should be. Since helm is reading hot the impeller, t-stat, and circulating pump are things I would first suspect. Exhaust is down stream and lots of time does not result in the helm gauge reading hot.

Whit that said being that you do not know the condition of the exhaust I would pull the elbow and inspect the water jackets for corrosion.

Ok Mike, call me AJ....and guess what, just passed a Harbor Freight being built near us. Score! I'm not a fan of cheap tools, but if it's "use once and destroy", why the heck not.

AJ I hope you are not waiting for them to finish building the store to buy the IR sensor

Some of there stuff actually last for 2 or more uses
