Well Geoff & I were talking to a Mercury Rep. at the boat show about the opti-max 150HP Two Stroke it weighs about the same as my 75HP F/S so we were thinking twice the horse power HMMM!

But suprise suprise he told us for our boats better off to stick with the Four Strokes twice the Torq Range ! & thats what yer want to get the boat up outa the water !! Lots of Torq

i hope you were wise enough to not buy into his sales pitch. if you beleived you could even begin to compete with a 150, well lets not even think about it.its just to far fetched.

Is it just coincidence that salesmen state things that are not posted anywhere If you look at any of the outboard web sites nowhere does it give the actual torque produced. They will state the HP but just give general statements when it comes to torque.

His comparision was HP being equal versus 2 stroke an 4 stoke , if you check the torq range of my merc 75hp its better than that of the bigger merc 90-115hp eng.s " same eng, block" so it is better suited to our boats you'll get far better hole shot , better range of cruising speeds and a much better fuel comsumption , the two bigger HP eng will have a little more top end speed but becuase they torq range is less they will take longer to get up their & eat away much more fuel in the process their better suited for bass boats & speed boats alike that are far lighter in weight & better hull designed for speed !

I don't know about that because when I use my engine it is usually at one of three speeds:
WOT which doesn't take that long with any engine to get there.
Trolling which is basically at idle going 2-4MPH.
Coming back in the dark with no wind or in a really bad storm day or night moving at 6-8MPH which is where what you said will hold water.
It tells me that the 75HP has low end torque curve like a strait 6 in a jeep (excellent for Rockcrawling) compared to the V-6 that is higher (better top end). So to sum it up for me the higher 115hp merc would be better for me 2/3 of the time.

maybe for your boat if she is lightly loaded and factor in the X has a flat bottom versus my M heavely loaded for living in & a rounded hull with a 15deg deadraise also the bigger "longer" the torq range an eng has gives it a much wider range of prop pitch to use acordingly !

I have a Honda BF50. So far the problems have been 2 bad voltage regulators and a rusted out tube which holds the steering and tilt. Also the tilt motor is rusting. The motor is quiet, dependable and good on gas. Also the initial price was low. As to performance, I get about 13 to 15 knots out of the boat, but it seems happiest at about 4500RPM and about 11 knots.

If you really want some power on your Mac, try this motor

Think i could fit both on my mac?

Wow!

Doya think twin 7's would blow wake on the intercoastal coast guard boys?

YeeeeeHaaaaw!

Ok, it's a few years down the road from the last post on this topic and motors have developed since. Is everyone still happy with the ETEC 60 only option because I'd like to run a 75hp motor on a late 2014, 26M.

My ETEC-60 is three years old without a single issue, zero maintenance. Just add gas and if you're running WOT it will take a quart of oil about every 24 gallons which is convenient because I just top off at the fuel dock. At low speed it doesn't use a measurable amount of oil.

Starts every time right off the bat no matter how long its been sitting. I've been able to pull start it in testing relatively easily. It's been a fantastic motor. I may replace it with the ETEC-90 in the far future when its time to repower.

A $50 cable lets you plug it into your chartplotter and get all the fuel consumption, engine hours, and RPM data. Very easy to setup.

I think it was Captain Victor that put a 90 horse on a Mac M boat? It was so big he could not even tilt it all the way out of the water.

There is a vid somewhere of him going WOT with that big motor - not sure how big it was but it was big.

Can't do a full tilt up with a 70 either.
