Author Topic:   40hp on a Montauk?????

Am looking at a new Montauk, live in Germany
where we have a restriction (!) on outboard engines. I am limited to a four stroke and 40 hp. I am considering the new Merc injection. Does anyone know if this boat will plane with a 40 and 4 on board? Our speed limit is 40kmh (about 25mph), I don't think that should be an issue!

Thank You,

Years ago my father had a Nausett with a 40hp johnson. They claim it will do like 430+mph and he said he never had any problems with 4 adults, until he replaced it with a 100hp:)If that is all you can do, I think you will be ok. can't be much slower than a 50hp and many here are happy with it.

That is 30+ not 430+

got the 430, very fast!
Is a Nausett the same as the Montauk?

Thanks Again

According to the BW website the 2002 model Montauk comes standard with a 40HP 2 stroke.
Montauks will plane at 12 mph so with 4 aboard it's quite possible.

I just went to the Whaler website. They may have updated their site bacuse the lastest standard motor seems to be the 90HP 2 stroke, with 60 & 90 4 stroke available as options. I might be looking at the wrong place, but this was where I saw it:

My 1999 Montauk with a Merc 50/4 stroke tops out in the low 30s with 2 adults and around 400 lbs of fuel and other goodies on board. The 40/4 stroke should work OK.

captndon- How far are you from Ranstein? I work for Boeing and have been sent over here for the next two months. If you end up getting that boat I'd like to go out on it, would be willing to split the gas. Plus it would be cool to go out over here.

Traveller, you're correct. When I looked at their site 3-4 weeks ago it said 40HP and I even commented about this on another thread that this must be a typo. Guess BW_is_ monitoring this site.

I may have been correct, but my spelling was awful! No wonder there is a caution about drowziness on a bottle of NyQuil!!

I saw it a few weeks ago too. I think it was minimum horse power if I'm not mistaken. Couldn't believe it was that low.

Minimum HP is 35. I know a few weeks ago they had the specs stating that the standard engine package was a 40HP two stroke.
I have a 50HP 4 stroke Merc on my Montauk and it'll do 34 mph WOT. I'm real pleased with this set up. If I was looking for a new engine today I'd opt for the Merc 60HP four stroke EFI engine.

Thanks for the response, the limit I have is 40hp and 4 stroke, I am going to order the typ Merc F40 EFI/ELPTB whatever that means.
Do you know of this motor?

What is WOT?

We can only go 25mph Max, my concern is plane-ing with 4 adults and fishing gear
on board. Do I need another type prop?

That engine model sounds like a four stroke 40 HP with electronic fuel injection, electric start, power tilt and trim. The B suffix makes me think that this is a Big Foot model.

WOT = Wide Open Throttle (another one of those damn American initialisms).

Is this a Belgian spec or US spec? Do engines in this HP range have to meet a COM I european emmission standard?

You definately want a 3 or 4 blade stainless steel prop. Merc offers the Vengeance 3 blade or the Trophy Sport 4 blade for that engine.

Okay, got it,

The motor is being made in Belgium, and the
"B" is probably for the special Bodensee designation (loudness/emmissions).

How do I determine the correct prop size/number of blades for this config?

I will check with the dealer here in Germany but there are not toooo many montauks here on bodensee.

Don, I was fortunate enough to visit the Bodensee last week, and of course was dreaming of running my Montauk on that beautiful lake! If you outfit your Montauk to minimize weight and maximize trim and balance, you will probably get satisfactory performance. Adding a Doel-Fin and dialing in the ideal pitch prop will help. My heavy Montauk will plane at only 14 mph, so a 40 hp with a good torque will surely be able to get you on plane. A standard model 17 may save a bit of weight, but the center console is a much more comfortable configuration in my opinion.

Good Luck

I have a 1965 Montauk with a 45 hp Honda. Top end is 28-29 mph at 6000 rpm and 18 mph at 4500 rpm with three adults aboard. I had to put a 11.75" X 12" alum. prop on (can't find a stainless steel one with these measurements). The old boat works great and gets about 7 mpg at 4500 rpm.

Good Luck with your new motor, David

Interesting that in Germany there are no speed limits on the Autobahn, yet recreational boats are limited!

I am also heartened to hear from other Whaler owners whose boats don't quite reach 50+ MPH at WOT. I though my 36 MPH top speed was way under the norm, but perhaps not.

captndon - I found this under the Boston Whaler Website calendar in case you are interested in seeing a whaler at a boatshow.
