Since the old 115hp '86 Mariner on my '77 Montauk is still running OK,I have been lurking around patiently, waiting for the ideal deal on a replacement to emerge. I believe that, for my purposes, 70 hp is the minimum power needed. Also, for my purposes, I've been looking for the lightest weight engine with the most hp, with the Yamaha and Nissan 70 hp's seeming to be optimum at about 225 lbs. The boat is primarily for fishing with ice, dual batteries, live bait tank,guests etc. contributing to weight.
Now, as life likes to do to us, I've been thrown a curve and would appreciate advice. I found a mint/showroom 1992 Mercury 75. The owner says that it has less than 200hrs. Its believable: I couldn't find a speck, much less a scratch, on it. As a used motor, it seems perfect. It is my understanding that it weighs 288 lbs - same as the 90 hp for the same year. The asking price is higher than average for the age, but probably close to fair.
Qestion: Does anyone have experience with this engine on a 17' Montauk? If I decide to go for the higher weight - 288#, should I hold out for a 90hp. What advice can you give?
Advice would be gratefully appreciated. We will be talking again Monday.

I have 98 90 hp Merc it weighs 308 lbs on my Montauk
I have 30 gal bait tank in the back with two batteries.
The weight is fine ,but I would not want to go too much more.
With any used engine there is a risk.
Check out the compression and the lower unit.
The 75 should be fine unless you pulling big skiers out of the water.

If the yamaha 70 weighs in at 225, I beleive the 90 Yamaha weighs only about 25 more pounds, that isn`t much, but you gain 20 more horses and some more torque, I say go 90 Yamaha :) Jack.

How much is he asking? Low hour outbopards are not always a blessing. Outboards do not like to sit, they like to run. Price would be my determining factor....so how much and what does it include?

Asking price is $2.5k. I'm thinking that might be a little high. Includes no prop, and controls haven't been discussed yet. We will talk tomorrow.

Nada value retail is about $1700
$2500 is a lot for a 10 + year old motor 75 hp motor

too much...guy here bought a 2001 or so 75 Merc for about $3500 new or slightly used I believe.

Thanks for the advice guys. It is a beauty, but I came to the conclusion that it just wasn't my motor. I called the owner and told him that I would have to let it pass. I kinda had the feeling that if I were going to have the weight of a 90hp, I should have 90hp. The cost/age factor also was considered. Still looking (and lurking)for a lightweight 2s 70-90hp.

Someone here is selling a Merc 90 2-stroke off of a new 170 Montauk.
