Help choosing an engine for my SIB
my first post here.. I've only been in the boating world for about 3 years now.. and my first 2 years were with an Intex Mariner 4 w/Minn Kota trolling motor. I primarily boat to go fishing and trolling...
I sold the mariner last year, and picked up a Salter Mountaineer 12' inflatable SIB. I had a 2.5hp tohatsu with it, but sold it and picked up an older 1999 Nissan 9.8 2-stroke.
Huge improvement, but trolling with it stinks.. so I've started to look at bigger 4-stroke options that I can still troll with. MY boat transom is rated for 20hp/325lbs.
I live in Calgary, AB Canada and locally I've seen a motor that's caught my attention.. the new 2017 Yamaha F25.. its 126lbs and has some slick features to help with trolling... only problem is that its about $4350 CAD to take it home.
The other option is a Mercury 20hp 4-stroke from Bass Pro. Its 10 lbs lighter than the 25hp Yamaha, but is more simple (no trolling adjustments etc)... the kicker here is that I can get this motor new from Bass Pro for $2700 CAD out the door...
so $1650 less than the Yamaha.. that's a considerable amount for 5hp, new tech and the trolling rpm trim....
I know these things are investments, but is it worth it? Can I troll with a Merc 20hp without adding or modifying things to get a good trolling speed?
Is the Merc less reliable? harder to maintain? etc.. I'd like to know everyone pros/cons?
