Wow , did it keep climbing or ?

No...it would then drop back down. It would cycle..but just get a little hotter than it probably should. It seemed to run cooler when drives were tucked to 2-3.

Again...I may be a lil paranoid given my past experiences.

Eddie will figure it out Im sure....

And that's what they should do. Eric's does that as long as the water pressure stays where it should. It was only when it dropped to below 20 psi that the temps went up. Not sure why but we'll find out.

Yes as you know Eddie my boat never had big water pressure even with the old engines , even now with supplying through the main center p u I have probably gained a couple pounds , running at 50-60 I have about 12-14 on port and about 8 or so on starboard , but as I run fast it does keep increasing never high . It did not change much from pulling through the drives to this setup .

Seriously??? Wow. Mabye the fact that your lowers are now 2" higher on the transom and do not pull water through them may be what the difference is???

Still surprised that with the large notch pickup that you dont have more pressure than before? Hmmmmm....

I meant going from sportmasters , pulling water through them verses picking up only from hull , I was prepared for high water pressure so when I put the big strainer in I installed 2 relief valves on it and dual dumps but I guess it wasnt needed .

Have you come to a solution on the water pressure and oil temp?

No sir. Still having issues. Ill let Eddie explain. Very frustrating.

You were absolutly correct Mark. I disconnected the drives' water hoses from the strainer. I tie wrapped them up to the railing and let them dump overboard. Up to 90 mph there is absolutely nothing coming out of them. I didn't run any harder because the water pressure in the engines was dropping as well at the higher speeds.

I talked with Rick at IMCO and he told me that they have had that problem before. However, it was with much higher drives. He said that these should see some water. ANyway, he told me to open up the pickup in the lower. After looking at Solidworks, there is 5" that can be opened up. He said to start with 2" and see what it does. That's what we are currently doing.

eddie - can you explain or show an illustration of the 5" you can open up?
