I dont run either setup but heres what I can conclude-

With the 90 you will have more speed, lower planing speed, Not as much work for the engine thus longer engine life

With the 60 the engine will work harder and thus more stress and maybe even more fuel consumption. You will ahve less speed and it will take longer to get on a plane.

60 is the min horsepower on that model(i think) and I have never heard anybody say they wished they hadnt gone with the maximum horsepower. If you are on a tight budget and you are goin to be just cruising, maybe the 60 will be okay, but If it were me, there would be 1 90 or at the least a 75 sitting on the back. You wont be dissapointed with the max!

The mass majority on this forum believe the MT 170 should be rated for 115 hp... Most believe 90 hp would be minimum and would not have anything less then 90 hp....

Several members have installed 115 hp on their MT 170 and are very happy..

A pair of 60's would be very cool on a 170!

I consider the 60HP BigFoot 4-stroke EFI satisfactory on our 900 lb 150 Sport, but it wouldn't please the hot-rodders on this forum. I'm sure it's satisfactory on a classic 17 of similar weight for those with similar conservative tastes in speed.

I don't think that even I would find it adequate on a 1400 lb 170.
