This last issue is when the engine simply wont start and it could be the result of several issues.

Pontoon motor too low. Or if you are already at 6000 raising the motor may allow you to move up one increment in prop pitch to stay at 6000 but go faster. Motor is great too. Posted by 4 years ago.

Smoke from the exhaust could be caused by contaminated fuel a failure with the fuel injector or incorrect oil levels which can be either too high or too low. Engine Sputtering or Losing Power If your boat feels like it is slowing down and you know you are not running out of gas you could be wondering what is going on. I went and checked out my boat and the motor seems WAY too low.

Its a good 8 from the cavitation play to the bottom of the transom with the boat and cav. Attached is a picture of it sitting in the water with no one on it. Outboard motor shaft lengths are standardized to fit 15-inch 20-inch and 25-inch transoms.

Last year I bought a very old pontoon and I have been happy with it but I do get cavitation when I turn. It helps a little when I trim up the engine but still a lot of water splash on the engine. I never seen a motor that big on a pontoon.

In Godfrey Pontoon Boats Forum. Selling for 8000 or best offer. In lower mounting the engine is set lower than the recommended standard.

How do you know if your outboard is too low. At the dock the plate is just below the surface but even at low speeds it cavitates. The motor on the back is too big.
