Nissan 6 HP 4 cycles

Thanks for the thoughtful responses. I think I will throw a few wing nuts on the engine locking bolts, that should allow enabling of the motor in a pinch. (Written from a slightly larger ship heading south and skippered by a mouse named Mickey) hmm. Taking one for the team.

Holy Moley! You are freaking MacGyver, Paul! I'm further impressed that your GoPro didn't record a river of expletives to go along with your quick thinking fix. Glad you're OK.

Zincs, aluminum OB's, white mush.

White mush could be aluminum oxide,

or corroded aluminum mush.

Maybe yer zincs aren't working,

or missing, or too small, or too large.

Zinc is in place and neither I nor the marina could remove it last month (it is the little square one that is OEM) because it had swollen a bit in the square recess but was still present and when I scraped it it still has some meat. They said we'd try to remove it at the end of the season, basically next week. Maybe it is corroded aluminum mush. It is in the aluminum carburetor after all.

I've been fighting the ethanol fuel issues for several years now . I was happy to see that Tohatsu now has a new 5 hp/6 horse power propane fueled engine similar to the gasoline powered one in all respects. Since it was designed based on the same motor that we all have and love, it shouldn't have the mechanical issues of the LEHR propane engines which are cheaply manufactured in China. I don't know – – it looks like they made the tiller 5 inches longer which means it may not fit in our well anymore! The dimensions look exactly the same as the models most of us have however, the length from the back of the Motor cowling to the very front tip of the tiller goes from 26 inches to 31 inches, 5 inches more. And this isn't just on this propane model, it's on all the models and it looks like they have increased length of the tiller. Hmmmm. If the tiller only rotates as far back as my current motor does that would leave a couple inches of the tiller sticking up preventing closure of the lid to the well. If I were to try to put one of these motors into the well with the tiller facing into the cockpit and sticking through the opening instead of vertically, that may be hard to do or maybe impossible. I guess I'll have to see . Anyone have one of the new models with the longer tiller? How does it fit? These motors are very reliable mechanically. But I'm afraid that the gasoline we have to put in them causes us to have to take exceptional actions to keep them running reliably .

Carl Alberg designs are legendary for their steering instability while motoring slowly astern. Will it go port or starboard? Toss a coin!

One of the great features of having an outboard in a well is the ability to rotate it for steerage while motoring astern at very low speed. Tightening the rotation friction on the engine to prevent it from wandering around while motoring forward prevents rotation in reverse. So, if you use this friction adjustment, you must reset it constantly. And at least with my engine, the friction can't be set tightly enough to stop wandering while underway.

If grease from the rotation housing ever contaminates the friction adjustment, the adjustment becomes completely ineffective.

Here's photo of how I solved the problem.
