Hey guys,

would appreciate any help on this matter.

1075 running good at 65, 70 mph. When I start trimming the boat out I’m getting overheating on the starboard engine and it’s being thrown in guardian.

i have rebuilt the pumps, gone through the complete cooling system and all is well.

water pressure is 18 to 23 psi.

thanks

is this something new?and where do you boat?

I live overseas.

i bought the boat from the us and have been having this issue.

can you post a pic of your water pick ups.what area of the US was the bought from.I'm suspecting corrosion in the water path around the bell housing may be the problem.

attached picture of water pick up. I have gone through everything. My mechanic wants to adjust the pick ups next as he believes due the water density here it’s not biting hard enough

Is there enough hose length to swap the inlet hoses from side to side ( at the transom) and see if the problem switches to the other side?

i do not believe so

does this boat have 1 sea strainer.as for the water pick ups,,someone was working on them for more water,,can see the welding.I'd put a groove(more like a triangle groove) in the bottom of the boat in line w/ the water pick ups.if non of these tricks don't work.time to pull the heads,they're probably rotted.
if you have 1 sea strainer,try adding a second one.

Each pick up has its own strainer.

i don’t believe the heads are rotten. I was told the engine was rebuilt 15 hours ago. I have bought it from a very reputable person.
