Can't open cover on a US Marine Force 50

[IdahoPotato]

I don't see any lever to release the cover on my white US Marine Force 50 engine. What gives? I thought maybe its a push down pull up?? Help, I need to diagnose a 13 year sitter....

Under the front of the cowling on the bottom should be a lever that moves that opens the cowl.

Thanks. That was pretty well hidden. Got it open and it looks pretty clean for a 1986. I like the white. Looks much cleaner and easier to see any leaks.

The 80's 50hp. One of the better runners from Force/Chrysler.
This motor runs on one cylinder almost as good as 2.
Use good oil and replace the impeller.

You do a compression test?

I'm going to do a compression test soon. I spayed the cylinders and want to let it rest. Rotate. Rest for a couple days for the heck of it. I'm sure the impellers toast but Im waiting to see if I want to get any other parts in the order.

That's a good idea.......been sitting up for a long time.

Spraying can make it harder to start.
IF?? the plugs didn't have rust on them when you took them out, the cylinders should be ok.
You can spray through the front of the carb to lube the bearings. Just don't overdo the spray.
Initial startup: make sure the cavitation plate is at least 4"-6" under the water or the muffs are the right ones or duct taped to seal them before you get it wet. The pics are the right ones for your motor. Others will fitbut can cause it to overheat.
