Universal Diesel engine no power to prop

[Fox1134]

Ahoy all,

I recently bought a Catalina 30 and have run into an issue.

I am able to start the engine and it sounds/ runs fine. There were some overheating problems but after clearing the water intake of growth I haven’t had that issue since.

The problem I do have is no matter how much throttle I give the engine while it’s in gear, forward or reverse, there is not enough power/ speed for us to move. The prop is spinning as I can see disturbances in the water and we have some motion from prop walk. I have cleaned the prop shaft and jiggled the prop to check the cutlass bearing. All seemed fine. There is still some growth I can’t get off of the prop but nothing huge

Any ideas for what could be causing this problem?

Thanks!

Sounds like a possible lack of fuel. Fuel filters, tank vent, pickup tube, throttle linkage, etc.

Gotcha I’ll take a look thanks!

Anything I should check with the transmission?

Just that it's full of clean fluid. It's usually recommended to change old, dirty fluid 3 times in a row. Run it in gear for a few minutes between changes.

how much growth on the prop? make sure you get if off.
