Re: What size kicker?!?
I have two of the 6HP OMC's and a 9.9, plus a 3.3 and 8HP Merc's for Kickers, there were others in the past too.
I would never use the 3.3 Merc for trolling, it's loud and vibrates, but it is strong. It’s similar to the 1.5 and 2HP OMCs I've had in the past.
I have used the smaller 3 and 4HP OMCs a great deal and they are very good motors if you need a light weight kicker. The 4HP OMCs were light and trolled very well, With just me I could even plane a small aluminum boat with one.
The 6’s aren’t much different, just more power and slightly more noise. I have had one since new (1967 to 69 or so, can’t remember right now) and it has needed almost zero repair work (new points, carb rebuild kit, water pump) since new. It has been used to troll day after day, all day long in both fresh and salt water, still runs great. I was trying to justify buying a new kicker about 15 years ago to replace it, but it just kept running with no issues.
The 9.9 (1979) has been almost as trouble free, it was used in the salt for many years and had some build up in the water passages, the old owner never flushed it. I cleaned it out, replaced the head gasket (over heated due the build up) and it has run great for the last 14 years. It might be a little quieter than the 6HP when trolling
The 1997 8HP Merc is the one I use the most, in fact the others have sat unused for the last 4 years. It is quieter, very easy to start and has the shift in the throttle feature, which works great for the type of fishing we do.
All of these motors work great for trolling, the 8HP Merc is only about 14 years old though, so it’s still too new for a long term test.
My next trolling motor will be a 4 stroke, but I need to find a good reason to buy a new(er) one, so far it’s been difficult for me to justify buying a new one when I have four that still run fine.
