Still undecided on the type of motor to repower my 15 classic. I use my boat to fish and dive. Just need it to get me out there. I'm leaning toward the suzuki 50 efi 4 stroke. Does anyone have first hand experience with this motor? How about the 50 4 stroke mercury efi?

The zuki 4 strokes are great engines and from what I understand the best MPG and quieter. The Zuki is EFI where the Merc is not. Go for the Merc 60efi instead. I would go with your best deal and dealer support(if you care).

I'm considering the Merc. 60 efi 4 stroke for my 79' Montauk. The only efi 4s 60hp out there and weighs about 240 lbs,I think. Do you think I can get up and plane out ok with this set-up?
Thanks for any input.

I run a Merc 50 4 stroke on my 99 Montauk. Hole shot is good and top speed per GPS is 33 MPH. That 60 should be great.

Say, Bones.

Johnson and Suzuki offer EFI 4 stroke 60s. Same base engine as the DF70.

Thanks Dick and JB,

I'm replacing the original 70 hp 79' merc so I'm a little partial.
Is there a prop you would recomend for the 60 hp 4-stroke/Montauk compo?
Got a base price of $5650 (called 10 dealers) for this engine plus installation and will most likely order it Monday.
It will be so nice to get back on the water with an engine I don't have to cross my fingers for.

Bones, after you get it and break it in, please give a full report on performance and such. I use to be against Mercury engines when the older ones didn`t apeal to me, but that EFI 60 4-stroker really seams like the perfect choice for my `16 Currituck if my 85h.p. Johnson goes down for the count. The EFI-HP-Weight is my reason for leaning towards the Mercury product. I am not a big Brunswick fan, but that engine sounds to good for the reasons described above!! Also, I beleive it will troll properly without a kicker, although I heard slow speeds are bad for leakage on 4-strokes, fact or fiction, if fact it may be a very bad choice for me as I troll for Bass and Walleye alot and mostly.

I,ll be sure to let you know. Spec.s on the 70 hp 4s Suzuki weighs in at 335 lbs v.s. 60 hp merc. described above at 244 lbs. Both are injected. I don't know if there is any diference in the injection method?

Like Dick, I have a 50 hp 4 stroke on my 16/17 (Katama); I've got a Yamaha with a 13 pitch aluminum prop, and I get 30 mph GPS at 5900 WOT (mine is a Bigfoot-like "High Thrust," meaning its gear ratio is 2.3 rather than 1.8, which explains the slower top end than Dick's). My old boat jumps almost instantly onto plane, and cruises comfortably at 15-20 mph. I'm burning 1.25 gallons of gas per hour on the move...can't even measure fuel use when trolling. The motor weighs 243 lbs. I'm very pleased with this silent, smokeless set-up.

I would imagine the EFI 60 h.p. Mercury 4-stroker should get you at least 35, but I would guess alittle more, since Dick`s is a 50 without EFI. Man, I would love to see that 60 on the back of my Currituck!! I would even shed 20-30 lbs. off of the backend!! Jack.

We have run the suzuki 50 on an ancient
whaler 16 for a year now. Wonderful motor.
slight vibration at idle, smooth everywhere else. Quiet, quick, fuel efficient. highly recommended.

Yes painful...
Rewarding I hope. I've ordered the EFI 60hp 4 stroke and if I'm lucky it will be on my boat by the end of next week. I'll post some mph at different rpms using the gps. I live in Huntington Beach, Ca. and the 4-stroke has an excellent reputation here in the boating circles and is becoming almost a requirement as far as new engines sales go (EPA). I take my Montauk to Catilina often and I'll be a lot less nervous about it with a new motor on the back.
There is such a wealth of information on this web site, it has helped me tremendously. My thanks to the founder.
I can't wait to get back out on the ocean now that springs here.
Thanks you guys for the input.

You'll love the Mercury four-stroke 60. I have the Yamaha counterpart, and it is a pleasure to run. Best of luck with your new toy!
