[I] just bought a 1986 Newport 17 (from a friend of a friend). The boat is in really nice shape. [I] purchased only a hull. What type, brand, and horsepower engine should I buy? I am new to boating so I have no idea. I will be using the boat for mostly fishing and probably do not need the maximum power (which I think 100-HP), but I really have no idea. Any suggestions? Any help greatly appreciated.

The Merc 90hp Optimax would be ideal.

That's quite a can of worms to open on your first post. I would suggest you use the search function and look for info on repowering the Newport or Montauk. You will find that this is a much discussed topic. There are some great reference articles on the subject as well.

You will find everything from comparisons on the low emissions 90 hp motors to topics on the performance of various motors on the 16'7" hull. You will also find a number of great opinions on what the best motor is.

The best thing to do is research and find out what is best for your needs and situation. Ask yourself where you are going to use it, if you are going to have lots of cargo/people and if you are going to tow anyone behind the boat.

I just repowered my 1988 Montauk after a year long research project to find the best motor. I found that there are a lot of great choices out there. I don't think you can really go wrong with today's power. My personal thought is that you go with a 90 as it offers all the power you need and the new ones are fairly gentle on gas. That said, I have also heard great things about the Suzuki 70.

Thanks for the info, I appreciate it.

To save money you may want to buy the same brand motor that was previously rigged on it. Changing brands would most likely require buying all new rigging. You may be able to use the existing rigging.

I agree a 2 stroke 90hp would be a good overall match.

The first decision to make is the horsepower you want. Many have reported that 60 to 70-HP is enough for their needs on a 17-footer, yet at the same time others say a 115-HP is great. The 17-foot hull is very versatile, and it can be used with a variety of different motors of different weight and power.

Because you are new to boating, I very strongly suggest you locate a dealer in your area with whom you can have a good relationship. The presence of a strong dealer with a good repair shop and plenty of experience with a particular brand of outboard motor can be an important factor in deciding on a particular brand of outboard to buy.

There are probably more prior discussions about re-powering a 17-foot Boston Whaler than any other topic. You may find some of them will be interesting reading, and just about every word they contain will still be valid and have application for your decision.

I suggest you start by locating the REFERENCE section, then find the article on the 17-foot Boston Whaler. Read it thoroughly and follow all the links to other articles. This will give you a good background.

The REFERENCE section: http://continuouswave.com/whaler/reference/

The 17-foot sub-section in REFERENCE: http://continuouswave.com/whaler/reference/16-17/

An article on re-powering a 17-foot Whaler: http://continuouswave.com/whaler/reference/16-17/repower.html

This last article contains links to many more. You can also use the search function to find even more.

Read all of that material and return to this thread to let us know if it was helpful. You may also have some more focused questions. And check around for a strong dealer who can be of service. Drop in and see if you like the guy.

I have the exact same boat. Repowered a year ago with a Suzuki DF70 four-stroke. I do not like [the Suzuki DF70 four-stroke]at all. Well, OK, it runs great and gets great mileage, but it is way, way too heavy for the boat, no matter what many will say here. [The NEWPORT 17 with a Suzuki DF70 four-stroke] performs poorly, loads the boat down. I can't emphasize enough.

A light two-stroke 70-HP or 90-HP is the ONLY way to go. I have had both a 70 and a 90, and would go back in a heart beat.

You can compare a number of 90-HP low-emission motors in
