Start Up After Winterization --1986 2001 Nautique

Good Evening

I started up my 1986 Ski Nautique 2001 and it is running hot. I undid all the items that I did for the winterization, I changed the oil. I am thinking I missed something. Can someone please help me. I ran the boat on the lake today and normally it used to run in the 160f range. Today it was running in the 220f range. Lots of smell, exhaust manifolds very hot. I am thinking I missed something. Hopefully someone will be able to point me in a direction.

My last run of the season before winterization, no problems. The boat ran as it has always ran for me over the last few years.

Thanks!

Did you replace the impeller?

Thank you to those that have replied thus far.

Some do some don't, but first use a nut driver(not a screw driver) and tighten all the hose clamps. The slightest amount of air suction can be a culprit.

It is really easy to miss getting the key into the key-way. They like to fall out. Therefore the shaft is not able to catch and rotate the impeller. Put a dab of Vaseline into the key slot, that will hold it in place.

John,
It's inside the RWP (raw water pump) on the front of the engine. The pump is an add on to the typical automotive engine so it's pretty easy to spot. It's on the starboard side and has it's own belt drive to it. Another way to find it to follow the suction hose past. it's the next item downstream of the trans oil cooler.

Have you tried tightening everything up yet?

I found it I appreciate everyone's help!!

John, were are you in NC? I could try to give you a hand if needed. There are also more members in the state.

John,
When you get a chance, go to the manual section of the reference section. Print the engine manual for your boat. We certainly don't mind helping but looking at pictures is always a help plus, it may take us some time to get back to you.
