1976 Montauk Thoughts

Hello all - I am looking into picking up a [1976] Montauk and would like opinions as to how she looks sitting in the water. [I have] been reading about water intrusion. [The 1976 17 MONTAUK] looks good to me, but I would like others' thoughts.

The battery and 15-gallon fuel tank sit in rear of this boat.

It seems clear in the linked images that the fuel tank is under the reversible pilot seat, where it should be.

The book looks good; it seems to be floating on its painted waterline marks.

The bimini top looks like it was not a Wm. J. Mills & Co. product.

I agree with Jim, the static trim looks very good. Good luck with your possible purchase.

What I can expect for performance and speed running the 65-HP that comes with the 1976 MONTAUK? Assume the boat and engine are running properly. Thanks.

Rigged at the right height with a good stainless steel prop a 65-HP engine should allow a boat speed 32 to 34-MPH at WOT running solo and light.

For some analysis of boat speed for a MONTAUK 17 with various engine power, see

http://continuouswave.com/whaler/reference/16-17/repower.html

For some general performance predictions for a number of classic Boston Whaler boats, see

http://continuouswave.com/whaler/reference/performancePrediction.html

You can get an estimate of speed potential for any moderate speed planing-hull boat using the Crouch method if you know the following factors:

--total weight; for a MONTAUK 17 with a lighter engine, we can estimate about 1,700 to 1,800-lbs

--the propeller shaft horsepower; newer outboard engines are rated for propeller shaft horsepower; older engine were rated for crankshaft horsepower and should be derated perhaps five to 10 percent for shaft horsepower;

--the hull constant or hull factor in the Crouch method; for a classic rounded bottom Boston Whaler hull, use 190 as the constant for calculations in MPH units.

Using the following data:

--weight = 1,800-lbs
--propeller shaft power = 65-HP
--hull constant = 190

the Crouch method calculates top boat speed will be 36-MPH.
