1990 Ski Nautique Overheating

does the intake hose have to go under the tranny on its way to the strainer or can i take it over the tranny to the strainer and then to the transmission oil cooler.

I have a PCM 351. I have a sherwood raw water pump. I looked at a previous post it said the cam screw on the side of the pump should face the engine. Then today I found a post the had a sketch that showed the cam screw on the outside for a RR351, and The screw on the inside for a LH(GT-40) How should I have the pump installed?

Being a 1990 you probably have a LH rotation engine and a RH prop due to your transmission being a PCM 1:23 to 1

Looking at your transmission fluid thread, it doesn't say for sure what you have but the 1.23 to 1 is pretty likely.

If that's the case then you look at the picture at the LH drawing and the screw head will be facing in.

Keep in mind, If you have it installed backwards, it won't move any water

To verify your ENGINE rotation you could look and see which way the pulleys are turning.

Looking at the pulleys from the front of the engine they will turn CLOCKWISE for NORMAL rotation

If it's reverse rotation they'll turn COUNTERCLOCKWISE.

There are other ways too, but this works and is easy to look at with the engine running.

Based on what you've posted earlier in this thread, it sounds like you have it installed correctly.
