what are the best production 3 cyl engines

[Chaz]

Yam 70 CES used in the T850 class
( for sure they copied the OMC 75, 15" small gearbox, tall gears)

Of course they did. All they had to do was ride their Tohatsu puppy across the street to their export shop …. (トーハツ株式会社, Tōhatsu Kabushiki-gaisha)+OMC-BRP

and copy their own design …

good question, what did the Tohatsu line up look like in the 60's

They are solid motors in that range.

A lot like a early Hodaka …



Tuhatsu



Or maybe a Bridgestone …



Which morphed into the Yamatsu line-up we have today …

Sorry to keep this post going but so from what I hear the 86 to 88 are the better ones but I was given a 93 60hp tracker model so im guessing this is a non bridgeport but were the 93 models any good? Is it worth kicking around this dead horse

I always thought that the OMC 3-cyl series of engines were a masterpiece of design. They have a lot of power and are extremely reliable.

I'm pretty strong on saying that your 93 is a bridge port. the oval port came out in 94 and the carbs are made of plastic and aluminum. The oval port is a good motor too.
The 15" short shaft model is what you really want if you want to go fast. They are the only ones that came out with the nitro gear case.
