Re: Outboard advice for 22 footer
Did I miss what waters you are motoring in?
4hp is fine even in current for a 22 footer.
In the 4hp range you have the option of internal tank with external tank connections. It's true that 4hp and 6hp in a modern brandy new outboard will be about the same weight, and they'll also be stupid heavy (60+lbs).
An older good running 2 stroke 4hp will run you about 35lbs.
Some things to think about... if you rarely use a lot of fuel (seldom motor)... a large external tank gives LOTS of reserve, but also SITS a long time. Without starting another ethanol is crap debate... lets just say, sitting modern fuel isn't good for a motor.
If you are talking about buying new... I strongly recommend you consider buying a LEHR propane 5hp. My opinion is the initial outlay for a slightly pricier external tank (fiberglass), puts the motor slightly higher in price than its' equivalent 4 stroke gas, but it pays off in an easier to maintain cleaner running outboard.
If I were buying new, LEHR would be my first stop. I am told they are mostly the guts of a Yamaha. I think most of the modern small 4 strokes are made by Tohatsu
PS: I have no affiliation with them, and couldn't care less, I've just spent a small fortune maintaining motors over the last 4 years. I didn't buy my boat to maintain a motor, and hate working on them. I'd prefer something rock solid and nearly maintenance free. My 3.5 HP 2 stroke (when it runs right) gives me hull speed at 3/4 throttle.
