I have been advised that some of the Mercruiser Racing motors sense the oil temperature at the oil cooler output as apposed to the crank case or oil pump output pre oil cooler. The 180F oil temperature that you recorded has to be such.

I guess the important factor is that the intercoler dumps the cooling water rather than recirculates it back to the sea water plumping of the engine. The question is if that is the same or different than what Plane Silly's engine is plumbed to do.

I dunno... I will check it out when it gets light outside (tommorow)

Chris,

What is the diameter/size of the T fitting leg that feeds the intercooler? Any pictures of this item installed?

Thanks,

Bill

The t-fitting is installed right after the raw water pump, and feeds the inner-cooler with a 1/2 inch line.

Well I finally got in the mood to start working on my raft. After doing some more reading on here I got to looking at the hose that goes from the outdrive to the transom assy. It was slightly pinched up inside the gimble. I'm not sure if it was enough to cause my water flow problem but I guess its possible. I think I'm still going to put on the transom water pickup but I would like some input on the location. How far out from the center line can I go. I don't want to disrupt the water at the prop but I would think you need to be as close to the lowest point of the hull while at speed.
I would post some pics but I don't see how to do. I don't have the little paper clip at the top anymore. I will try to post them on another site and link them.

When you select "reply" to a thread the widow that opens where you type your response includes an "Additional Options" section below which includes a "Manage Attachments" button. Click that and follow the instructions to attach whatever.

Mine doesn't have the additional options section anymore. I think it is because I let my paid membership expire.

Plane Silly,

What is going on with your Rage upgrades?

I am holding off on the transom pickup until I do some more testing. Bob L recommended that I block off the 4 upper holes on the outdrive and see if that helps my press some. The weather has been crap here so it looks like another weed before I can get her in the water. I would still love to see a pic of a transom pickup on a Rage.
