There's so few options as motors it's different. Really mainly Mercury, Suzuki, and Yamaha now. Not much to cover.
I'd only consider Suzuki and Yamaha now, I think their reliability is going to be better than the Mercury. Look at offshore boats, mostly Suzuki's and Yamaha's.
I went with Suzuki because it's far cheaper and arguably one of the most reliable outboards out there.
I'm buying my, most likely, last boat. An Alumacraft Competitor 205 which is a Deep-V, multi species boat.
My last boat was a bass boat and that was the biggest mistake I ever made. Although the boat was fine I did not like 6 major things about it.
I am a bass fisherman but a Deep-V, multi-species boat is just better for me. After I ordered ordered my new boat I realized I wanted to start jigging for lake trout on Lake Superior and a bass boat wouldn't have been safe on that lake. I will have 2 Raptors on my boat which will sort of be in the way but there is no way to quick disconnect them yet.
** With the advent of trolling motors and shallow water anchors a lot of the benefits of a bass boat can be had in a Deep-V, multi-species boat such as fishing in place.
One of the benefits of bass boats was that the lower profile kept the wind from blowing you around as much wherein a taller, Deep-V boat would get much more easily blown around. That can be negated with a trolling motor with Spotlock and/or shallow water anchors.
Also, with better design Deep-V boats are accepting larger and larger outboards allowing you to gain tremendous speed. Not as fast as a bass boat but even some into the 60mph+ range I believe.
With the new pods on the back of the Alumacraft Trophy and Competitors you can draft less water, go into shallower water than you used to be able to and mount a far larger motor, up to 350hp on the 205's (20.5" feet). This extra 100hp could maybe even get you close to the 70mph's which is pretty darn fast, but this is an estimate.
A bass boat wasn't for me because:
1.) Loss of floorspace:
With the layout of a bass boat you sit down to drive and that takes up approx. 3-4 feet of space. So if you have a 20' foot boat you really have a 16' foot boat. This sucks and is just the nature of bass boat design.
*** Many people are limited to boat size (length) due to their garage space.
If you want more actual boat footage and less wasted space and are limited in how long of a boat you can have you may want to look at a Deep-V, multi-species as you will get more usable floor space on the boat with the same length boat.
2.) Cannot fish sitting down:
You can sit in a chair that's in the cockpit of the boat and still fish comfortably in a multi-species boat. Much harder to do in a bass boat since you sit so low and the chair does not swivel.
3.) Grounded bass boat seats do not absorb wave impact, your back does:
I hit some hard waves with my bass boat and thought I broke my back one time. Having the chairs mounted to the floor leave you vulnerable to wave impact. It's just the way it is. I know some newer bass boats have cushioned seats now. How good they are, I don't know, I've heard you can still get whacked.
4.) Water comes over the back:
Whenever you stop fast (who doesn't) water comes over the back of the boat which sucks. Not a huge problem but it can make some stuff wet.
5.) Sit too low in the water for many docks:
I found that my boat sat so low that I would be sitting under the docks sometimes and it could scrape the top of your fiberglass gunwale up.
You definitely have to be careful.
6.) Harder to get in and out of the chair:
If you are getting up and down a lot from the seats it is a lot easier in a Deep-V, multi-species boat, it is like getting up and down from a chair.
If you are moving a lot or doing stuff where you are sitting up and sitting down a lot doing so in a bass boat takes it's toll on you at the end of the day. Not good as you get older which all of us are doing.
Having a Starter Boat, like a Starter Wife is a good idea to see what you like and don't like.
*** When it comes to electronics on a used boat my friend, a former tournament fisherman said, "If it's over 3 years old it's considered obsolete. So if a guy is trying to tell you that he has $15k in electronics but it's 5 years old than it's not worth that much anymore."
Not saying the electronics are not worth anything just not what they were new. Electronics do not retain their value like the boat does.
