I am considering re-powering my montauk. I have run a 88 hp Johnson and was happy with the torque and speed as I use the boat for a lot of skiing. Many have suggested going with a 90 hp Yamaha, but I am concerned the 3 cylinder may not perform like my old V-4. Any thoughts or suggestion??

Amen to Gvisco's comment, Julius.

The JohnnySuziRude DF70 seems to be an excellent choice for a Montauk.

Mine is a Suzi and is magic. Yesterday I took her out of "winter" storage, topped off the battery, pumped up the fuel primer and touched the starter. Just like a car!! Less than half a second later she purrs. This engine is quieter on the hose'n'ears than my son's Merc 90 2s is in the water.

In addition to GVisco and me, Bigshot recently repowered his Montauk from a Yammy 90 to a DF70. We have all become disciples of this engine.

Bigshot will be here shortly.

Sorry...just flew in from NJ. Man are my arms tired...bump.bump. bump.


90 Yamaha is a great engine on that boat. The 70efi is better. Only lost 2mph and although she lacks the "snap" the other benefits quickly make you forget about it.

I still think someone fills my gas tank when i am asleep.

Just had my 20 hour service done. complete diagnostics, valve adjustments, fluid changes, etc. $88. Oh yeah!

Thanks for the imput guys. Sounds strong from a lot of knowledgable people to go 4-stroke. Will expand my research to include your suggestions.

I have a 1998 90 hp 2-stroke Mercury on my Montauk.
It has all the power you need & plenty of guts and good on gas.Goes 40 mph.

Almost four years old and not one problem.
You get the most hp out of the Merc for the $
