That's a really good question that I don't have the answer to. I can't find the plate on it anywhere and the title doesn't include a model number for me to locate a manual with. I went with the smallest motor recommended for a 16' Jon boat. Edit to add: It looks like the max hp rating for a 16'...

Would you bother trying to get this crack fixed or just replace the wood and call it good? If you would fix it, would you get it welded or just slap a piece of 1/8” aluminum angle over the whole transom cap? I’m leaning towards the aluminum angle. If I put it on the inside, I can bolt/rivet it...

It’s an 88. I payed $500 for it and an older evinrude parts motor. Took the carb off yesterday and the gaskets still look ok from the outside but it absolutely reeked of bad gas. I’m debating whether to just give it a good soak in B-12 or totally rebuild it. I was already planning on doing the...

I thought I heard a bit of a rattle as well but assumed it was normal for a 2-stroke outboard. I suspect that a big part of the problem in the video was bad gas. When I pulled the carb, it reeked of stale gas.

Well I bought the motor. I only got about 60lbs of compression; but, it was even across both cylinders and I was using the pull cord with a HF compression tester so *shrug*. I know it was at least partially running a couple of weeks ago. I’m going to put a drill on it when I get home and see...

The guy sent me a couple videos of it running. It’s definitely going to need a carb clean at a minimum. It runs ok at idle but you can hear it start to bog when he gives it throttle. Thank you for the info about the compression. I’ve been reading up on the motors as much as I can but I hadn’t...

The electric starter is a “eventually” thing. I’ll do some basic diag to see what it needs but it is down towards the bottom of the list of things to work on.

Im figuring on new plugs, a seafoam treatment and a starter switch at a minimum. Possibly a carb rebuild kit, water pump, and starter as well. Compression test should come out around 100psi, right?

I'm currently working on fixing up and outfitting a 16' MonArk jon boat to chaise crappie and cats. Been fishing out of my folks' pontoon and it just doesn't work well on the stumpy lake that I like to fish. The MonArk looks like a turd but it just needs a lot of TLC. Finally got the 20+ year...

I'm currently working on a beater 1973 Monark 16' Jon Boat (model 1648, I think). It was a marina "run around" boat that they used and abused. It looks like a turd, the transom is rotten and the aluminum on top has started to split where the motor mounted, the drain hole is out of round and...

What are some things to watch out for on these motors? I’m going to look at what I believe is a 1990 Johnson 15 hp on Saturday. Dude says it runs good but could stand to have a tune up and the electric start doesn’t work. I know next to nothing about these motors other than that they have a...
