Yamaha 200 v6 on a 20' master angler?

[Jasnyder1]

So I've got a question for y'all, I have a 1992 Yamaha 200 v6 sitting in the barn that I don't know much about but I'm thinking on putting it on my master angler I'm redoing to get me back in the water and keep me from having to put a lot of money out for a four stroke. I am willing to spend some money to get it rebuilt and running good I just wanted to see what yall thought. I have a Hermco bracket for flotation on the back and I'm moving my batteries and fuel tank forward so im not too worried about the weight as with a four stroke. Are these motors pretty dependable normally? Any major flaws? Does anyone have any kind of performance or mpg numbers for one?

A bracket will shift your CG aft by 12-18", so the lighter your motor is the better. Even though the Hermco bracket has the most flotation of any bracket on the market, that doesn't help when you're on plane and the flotation tub is out of the water. esp. when trying to hang on plane at low speed for a more comfortable ride when you get into a nasty chop. Plan on adding a 4B stern lifting prop, trim tabs and an AV plate fin. If you haven't read this post, check it out.

that motor weighs 416 lbs and those motors are among the ones considered bulletproof.

Thinking of doing a similar re-power for my 1975 Sceptre 20'.

Have a 1994 Mariner 2.5L 175 XL (395lb), want to plug the I/O and add an Armstrong or Hermco bracket to hang the engine.

Let us know how it works out - seems like a lot of power.

It works good. Real good. I am a fan of the 200 2 stroke, good torque, good pickup, decent fuel economy. I have the HPDI and it runs very clean. I am cruising slower than possible by choice, usually around 23 knots and get very good fuel consumption. When it's flat I push it up to 32-33 with no issues. At that speed, I am probably 2+mpg. Flat out is 39 knots.

I have a 1993 yamaha 200 carb'd motor on the transom of my 20' seacraft. Its the SF model. Lightly loaded with just me in the boat, I can cruise at 28 mph burning about 8 gph which is 3.5 miles per gallon. Not bad for an old 2 stroke. My boat has no T-top but does have a 36 volt trolling motor on the bow and 4 batteries under the console. Original floor and the scuppers (out the transom now) are about an inch above the water line.

Thanks for the replies, I think I'm going to use it, it's there and it runs good so I figure I'll try it. I'll let you know what kind of numbers I can get out of it.
