Problem resolved on bad low speed running

Background: For several years I've had lousy low speed, no wake zone performance with the motors on my dink boat. They would start skipping and loading up, making low speed running a nightmare. I've tried numerous things to cure this, and several different motors, and all without success.

Well, I FINALLY figured it out: The boat is way too low in the water at low speed, forcing water to get into the lower cylinder. (Note how close the powerhead is to the water in the photo.) If I sit way forward, on the front deck, the problem goes away!

Anyone have an idea how I can get around this? The boat is used as a utility now and then, for transporting people and stuff from the big boat to shore, so I need to run at low speeds around anchored boats and in marinas.

Thanks,

Jeff

2.Make sure you have atleast a case of beer in the front as well
3.Fuel in front ,less fuel?

Cut a relief hole in the side of the tuner, above static waterline at rest.
Water is being sucked back into the cylinder on reversion as the tuner just becomes a vacuum funnel.
If you cut a hole or relief in the tuner, the vacuum is killed.

I like it, Andrew! (The case of beer up front has possibilities, too!) I might have to add a pipe to that hole, aimed downward, to keep the noise down. Neighbors, you understand.

Thanks all!

If you cut a hole in the leg, the tuner is inside as a separate casting, it's the one you really want the hole in. So you can cut through leg and tuner then plug the leg hole, leaving tuner open.
Start with a small hole and see how it goes.

Regards, Andrew.
