Thread subject: Whaler Central - Boston Whaler Boat Information and Photos :: Repowering 1965 Nauset

Boy, could I use some advice! I've recently acquired (at no cost!) a 1965 BW Nauset (I think...all the wood's gone, and a new console was installed with a BW RPS). A cousin had it for last 20 years, and had repowered it with a 1986 Yamaha 90. The Yamaha is seized up after several years of no use, and I'm faced with buying a new motor. I've never even had it in the water! So here are the questions for all you Whalers: a) What HP? I'm not interested in a rocket, but would like pull the family skiing. b) Two-Stroke vs. Four Stroke? Shouldn't I be concerned with weight on the transom, and floating level? c) What can you tell me about the ride on these older hulls? Things to watch for? My boating opportunities range from CenFL lakes to ICW to Atlantic to the East and Gulf of Mexico to the West.
Thanks!
Gregg

We have a current engine choice guide located in the article section.
http://www.whalercentral.com/readarti...ticle_id=5
2 stroke or 4 stroke is up to the individual and you will get everyone's opinion.
I personally prefer the 2 strokes and the lighter in weight, the better.
I would say 70 to 90 hp but others have good experience with 50 hp...
Good Luck in your decision.

Thanks, Joe. I hadn't seen your article, and it certainly answered my biggest question about weights. I haven't seen much price or weight differences in 70-90HP range, so I guess I'll stick with 90HP, and let pricing and features lead to the decision of 2stroke vs 4stroke.

Gregg,
Another thing to consider is your local dealer.
If you have a good local dealer, that can be a good selling point no matter what brand of engine.
I don't have any local dealers to speak of so I personally would buy an E-Tec because there is no maintenance (if nothing goes wrong) for 3 years. I don't want to take my boat and motor in without a 3 hour round trip each time I drop it off or pick it up just for an oil change or 20 hour service. That just wouldn't work for me.
The 2 strokes are lighter than the majority of 4 strokes although the 4 strokes are loosing weight.
For many of us that fish and troll, we also want a small kicker on the transom. So, a couple of lightweight 2 stroke motors would generally weigh a lot less than two 4 stroke motors.

Hi,
I just repowered my 64 nauset with a 4 stroke mercury (used to have a 1978 80hp 2-stroke). I found it on ebay for less than I could get any 2 stroke even a classic carbed.... even after the $250 delivery fee.
According to the table that joe put together, the merc is one of the heavier of the bunch. That being said, I don't notice it at all. My boat sits about an inch lower in the stern than it used to. That's where it ends.
The new motor is amazing. It's quiet, no fumes, and runs like a dream. I had 4 passengers, 12 gallons of fuel, and 100+ lbs of extra stuff, and she jumped out of the water with absolutly no hesistation. 42 mph... fully loaded at 5800 rpm. It will pull out a skiier no problem!
Everyone on here as their own opinions in terms of how to power a classic whaler, but in my experience, the 4 stroke is great.
I've got 7 hours so far, and I love it.
Good luck,
Joshua

I have an old blue myself and I just repowered it with a new 50 Hp Merc 2 stroke. I am very pleased with it but be advised you may need a jackplate to bolt it up. Also the two stroke use a little more fuel, I beleive Good luck

I have a 63 Nauset and just repowered. I put a 100 HP 4 stroke Yamaha on it (365 lbs) because I got a good deal on it. I run 46 MPH wide open. While the engine works great, I would recommend anybody repowering go with a Yamaha 2 stroke 90 HP. The weight is great (about 265 lbs) and great power. More than that being important though is your local dealer network. Stick with whatever manufacturer that has a good dealer network near you.

Thanks to you all! Now I'm checking e-bay, and finding some better deals on all kinds of engines. I'll get some pics in when I'm done!

I've run just about everything on 17's andmy favorit eis the 70 Suzuki 4 stroke. I would also consider the Yamaha/Merc 60 if you desire lighter wieght which in my mind is not an issue. The 90 Yamahas 2S are great/light engines but you can't beat a 4 stroke.

How much would you sell the ceased up motor for? I`m in Central Fl. also, 40 miles north of Tampa, and could pick it up.

Sorry, Binkie, I just noticed your question. I haven't given much thought to selling the seized Yamaha 90, figuring I might "part" it out. One used OB guy near Tampa said it would be worth $300-$400 to him (if I bought one of his engines).
