Leblanc Brothers 1610
Length 16'10"
Beam 8'1" amidships
Draws < 1' loaded
Weight ~ 1000 pounds dry

Fiberglass on wood fiberglass console (<100 pounds)
One starting battery (~30 pounds)
23 gallon fuel tank (190 pounds)
Leaning post (35 pounds)

All opinions are appreciated, boat will be run for harbor and coastal crusing from Cape Cod to Maine. Builder says that people have put 70-90s on them and getting up to 30 knots. I would *like* to run at 3/4 throttle running at 22 knots.

And if you wouldn't use a 23 gallon tank what would you use?

I would go with the new Yamaha 70 4 stroke, very light for a 4s.

Guess it's personal preference, I would power with a Suzuki DF90. The latest model Suzuki 90s are based on the older (which I have) DF70. They added variable valve timing and computer mapping to achieve the 20 extra ponies.

At 3/4 throttle you would burn what a 70HP of yesteryear burned. My DF70 has been bullet proof and economical for over 10 years.

Second part of your question, I would definitely carry a reserve 6 gal tank if the main tank is only 23 gallons. I do this in addition to my 40 gal tank for redundancy. At 3/4 throttle, there would be well over an hour's worth of fuel to get home.

one word "yup"

I like the e tecs but I think the DF90 would be the way to go. If its in the budget always go a little bigger as long as weight isnt an issue. Would rather run lower rpm's and make my motor last .

No, no jets on this one. We're keeping this simple here.
Outboards only...!

Ok

@F/V First Team, I think that might be excessive since the hull's only rated for 100 horsepower. But I like your thinking.

@Woundupmarine, I'm with you on that one (that's the brand I am leaning towards).
How many horses are you thinking?

The 75 and 90 are the same block so the weight difference should be minimal, id go with the 90. Just make sure you have it set up for the xd-100 oil, great engines!

You just answered your own question . 90 is the way to go. Either way
The Suzuki is a great motor, if you decide to go 4 stroke that would be my choice, but the e tec is a lot easier to work on and a bit lighter, I see your delima. Think they both have there pros and cons, tough call.

My vote is for the 80 Hp Suzuki 4 stroke. This is the model I have on my boat and it works well. They only made this model a couple of years, and you can find them new in the dealers' warehouses for a good deal since they want to get them out of inventory. I got a free 6 year warranty included from the factory. This should be plenty of power for your 16' boat.
