  • Mako 19...new OB?

    I have a 1970 Mako 19 with an 2003 90hp Mercury four stroke outboard. The Mako site says the maximum recommeded horsepower is 150. In 1970, that engine would have weight about 300lbs. Nowadays, most 150s weight more than 400lbs (for example the 2018 150hp H.O. Envirude E-tec weights 418lbs). My transom is solid but original height. Any ideas or recommendations what engine I could/should go with?

    I own a 1970 19 also. The bulk of people typically run 115's on them. Mine is currently outfitted with a 1996 115 Yamaha 2 Stroke. The transom on that hull is not reinforced for a big power four stroke engine. I would say a 90 horse four stroke would be about all I would ever hang on my hull.

    I would highly suggest going with a lower weight 2 stroke on that hull. They were originally setup for a two stroke and keeping on that path would yield the best results.

    Personally I would look for a 1990-2000 Yamaha 115 or 130 2 stroke. Thats my .02

      Rowch01,

      Thanks. Appreciate your $.02 but I already have a 03 Mercury OB. Its a heavy 4 stroke so the last thing I want to is buy an older OB. Thanks again.

        I would consider a used or new E-tec 135hp V4 I believe you would have great performance, and still sit high enough in the water to be comfortable. The 150 etec is a v6 and weighs significantly more...

            Understanding that everything costs money........

            Any thoughts on adding a flotation bracket? A full platform would also spread the load across a greater surface area, reducing the effects of more horsepower pushing on the transom. Also, it should help offset some of the weight increase.

              Do you keep the boat moored in the water or on a trailer? I would not worry about weight unless you have a self bailing issue and leave the boat unattended for days at a time. You can fill in the open parts of the transom with starboard or plastic lumber to keep the water out the back.
