Overheating
 

Hi...Have a 454, believe gen IV in an 89 Rogue. It keeps getting hot on me...Rebuilt the seawater pump, and replaced the recirc pump, as it looked original, and was pretty gnarley...Had the muffs on it, and it looked like it wouldn't take any water.....I'm going to make sure I put the hoses on correctly, but thought I had it...There's also some sort of flushing device in line between the seawater inlet and the seawater pump...Gonna yank that and make sure that's not my problem. Next up its the ps cooler...Is it easiest just to yank this thing to clean it? Kind of tough to get at. Can I just backflush from the recirc pump? How about in the drive...Is there anything there I might want to check? Thanks...Den

Ok...Hooked the hose up to the flush device, and it ran perfect...Suggestions? It has to be from the flush device backwards. I ran it before I had the drive on by inserting a hose into the water pickup on the bell housing. Of course, this was under pressure, so an air leak may not have beeen detected..Help?

Bravoe drives have a hose between the transom and the belhousing, it could be rotted or loose on one end. There is also an oring between the bell and the drive, but I doubt it is leaking that much.

How tough is that to get to? Do I need to pull the drive? Thanks...Den

You can see parts of the hose with the drive full up. That would give you and idea of general condition. However, to inspect the whole thing you'll need to remove the drive - there is a plastic insert in the drive end of the hose. The insert retains the hose in the bellhousing, and seals it against the bellhousing. But, they can break and could cause an air leak when on plane.

Thanks for the tip...It overheats on the muffs too..Won't suck water...

Also hate to bring this up, but running without being able to draw water in for some time may have damaged that impeller in the seawater pump. PITA I know, but you should probably take a look at it again, even after you find your problem in the back side. Using that garden hose on the flush port can deceive you into thinking impeller is ok, because you are already pressurizing water with the hose.

Yeah...Kinda thinking that myself...It won't be as bad now, since the bolts were just out ha ha!

Shouldn't there be enough water pressure from the muffs to force the water up the drive? My well pump kicks on at 50 psi, and shuts off at 70...Could my flush device be defective? There's water in it...If I had my hoses reversed, would it still have run cool from the flush device?
