Would like some info on the performance of a 2001 75hp Merc. 2 stroke with a 17 Montauk

I seem to recall reading a while ago, or perhaps it was in the archives that someone repowered with a 75hp merc and was getting outstanding results with it. If I'm not mistaken, they had a jackplate mounted on the back but something tells me they were hitting the mid-40's with the setup. Perhaps the original poster will respond with more informatation.
Good luck in your search!

I found that same post. 40+. Just wondering why there are not more out there. See alot of 90's and 70's

Reason being was Brunswick used the 75 as a base engine on the Montauk. Most people for a few hundred bucks upgraded to the 90hp being same weight and block, etc. On cheaper boats you may see people stay with the smaller but when spending $25k what is another $700 or so. I saw a good deal on a 75 on E-bay a while back somehwere around $4k brand new. They say you an get them at Bass pro shops for around $4600 I believe.

I've got a 1998 17' Standard, with 98 75 HP merc. 2 stroke and couldn't be happier. Top end is 43 MPH (GPS) with good accelleration, etc. Motor is economical to run and trouble free. I think it's really the same engine as the 90 (Same weight at 305 lbs) just derated to 75 HP. If I bought a 17' again and wanted a 2 stroke, I'd buy the same engine, not the 90.

What type of prop do you have?

I wanted to surprise you but I guess you know now. Now I can post 80 times about rigging and props.

Nope...if the 90hp runs a 20 or 21" you will run an 18 or 19". Rigging is easy, bolt her on and hook up the wires....see you are ready to go.

John, I am hurt that you didnt buy my '84 Merc 90 that we emailed about several months ago :( (Actually, I sold it for short money to the local Harbor master - I hope for my sake that it treats him right!)
Anyway to reinforce what Bigshot said, I am running a 21" pitch aluminum prop on my Merc 90 2s (mounted on a montauk). You are welcome to try it out on your 75 hp for comparison purposes before spending $$ on your own prop.
The 75 can't be much less power than the 90 if andy is getting 43 mph - heck, that is top speed in my boat.

Thanks for the info. Should receive motor in 3 weeks. Will rig in late april after I clean up the hull while the motor is off. Any suggestions on where to buy Ignition, Harness throttle control,Tach...? everything

E-bay or any marine surplus store is your best shot.
