Today's twitchy, scary, but successful boat ride

The "new" 58 16 ft Crestliner came with what turns out to be a pretty fair running 75hp V4. It ALSO came with an unknown condition 1974 Johnson 2 holer 50hp. It was lying in the boat, with mice inside. Turns out it is long shaft

I am sort of thinking that if/ when I rebuild the transom wood on the 16ft, I'll convert it to long shaft, and put this 50 on her, but I have no idea of it's condition

So the other day I got it (the 50) running in the test tank, and hoisted onto the little 14ft only to find that it would only run on one hole. "I think" its a bad/ intermittent coil, but when I got home it had spark on both cylinders I also thought maybe one carb was AFU

So I cleaned out the carbs, and put a pair of coils on it off a junk engine and went out today briefly

TWITCH AS ALL HELL. that huge prop REALLY controls that little boat. And since it's long shaft, it "pumps" water up and over the transom LOL. And it is REALLY twitchy, just touch the wheel and it is "off." AND WHEN YOU pull back the throttle you have to be REALLY careful as the prop drag tries to turn the boat one direction. Does this MUCH worse than the long shaft 75 I had on. BUT IT DOES RUN!!!

The prop on that thing is HUGE. The 75's have a tiny little high speed prop looks more like a 25-35hp

I can see your Johnson... ^^^

Cool adventure...

Looks like a white knuckles ride,,,

Twitchy indeed.
With the long shaft motor, you have "lowered the roll center to below the hull". sorta .
Very easy to roll it over on a turn with power.
Pls be careful.
Good luck

Yup. This was only to discover if it ran well, and is a one-time deal. You can't run it under much of a load in the tank. I may sell it, or as I said, convert the 16 ft to tall transom and put it on there and sell it
