Does anybody have a Mercury 60 hp four stroke on their montauk. What will it do top in? How does it perform?

If you have any choice at all, I'd opt for a 90HP. The 60HP BigFoot isn't very fast even on a much lighter 150 Sport. If you've already purchased one, it isn't a complete disaster.

Here's some discussion and link to BW's performance test:
I don't think that 170 owner's been back since.

It won't be a complete disaster by any means, depending upon your boating interests. Old pros and CW members Dick and Clark have had fifties on their Montauks and loved them, I had a fifty on my Katama and it was perfect for my uses, CW member Steve/17 Bodega is pleased with the fifty horse power-16/17 combination also. I note in your profile that you're a motorcycle enthusiast...if this means you're looking for top speed and lightning performance go with a larger motor, but for quiet, economical fishing and 18-24 mph cruising, a fifty four stroke does just fine and a sixty might just do a little better. I've written several detailed posts with performance data over the past year or might want to track them down through the CW research engine before you make your decision.

I just noticed Tony and I are talkin' about two completely different Montauks, me the 170, and he the classic 16'7. The latter is only a little heavier than our 150 Sport, and yet is 4" narrower, so the performance should be similar.

The 60HP BigFoot EFI runs about 35 mph lightly loaded on the 150 Sport, and probably 30 mph heavily loaded. Not as fast as it would be with larger motors, but more than fast enough for us.

I have a 75hp merc 2 stroke on a 96 17 standard converted to a montauk with a 31 gallon aluminum seat tank. I regularly go out 30 miles and get backed up in some seas sometime and with my 305 pound motor, I take quiet a bit of water over the stern. It doesn't really bother me cause I've filled the boat up on several occasions and I just power boat up and most of it goes back out over the stern. My point is that I'm thinking of going 4 stroke and I would hate to have 100 more pounds on the stern with the 75 or 90 hp four stroke. I've seen some classic montauks with the 75/90hp sitting in the water and it is just too heavy for the boat. The 60hp four stroke is much lighter, even lighter than my motor. I'm retiring soon and thinking of fuel economy with gas skyrocketing. What is the lightest four stroke on the market with the most hp for my boat. Dennis

The Yamaha High-Thrust 60HP is 255 lbs, 13 lbs lighter than the Merc BigFoot EFI 60HP, but I sure wouldn't give up the EFI for 13 lbs! This Yamaha uses the Merc 40/50/60 powerhead but with carbs instead of EFI. You'll want a 13-15" pitch prop for a classic 17 depending on load.

The carbureted Yamaha non-high-thrust 60HP is 244 lbs, and the small foot Merc EFI 60HP is 248 lbs. While the small foot may have a little less drag, it has a much higher gear ratio, meaning the prop pitch would have to be very flat, 10-12" to give the same thrust. I'd definitely opt for the high-thrust/BigFoot on a classic 17.

For what its worth,
I have the small foot 60hp merc EFI with a cupped stainless 14p prop that turns 5900RPM and gives me 41.1 mph gps with two adults (170lbs ea) child (35 lb) and 10 gallon gas on a 15ft striper (console and pedestal seats). I had planned to keep the motor if I upgraded to a 17ft. The added weight over 2 stroke (about 60lbs) was noticable. I can't imagine 100lbs more (four stroke suzuki 70hp) on a 15ft. I would love to hear if anyone has a 17ft montauk with a merc 60 efi smallfoot. Perhaps it would be useful to have a link section with various boat motor combinations (including prop/height/weight) with gps speeds that one could use a drop down menu to access. This site is already such an amazing repository of info-as a whaler owner I am truly grateful for the site
