Re: Good size kicker engine
Although this wasn't your question, I suggest thinking hard about the cost/benefit of a spare motor "just in case" and especially for a boat that size.
That's a lot of weight on the stern and you already have a heavy motor.
That's a large piece of idle equipment on a small transom.
That's a large wad of idle cash dollars, especially on a 1974 boat, even though it's a whaler (on a bayliner the kicker would be worth more than the boat).
Thief magnet. You will likely need to remove it for security.
If your main motor is relatively new, you won't be needing it. And probably not even when it gets old.
It has to be dependable. in order to be dependable it should be fairly new (big bucks) and you have to run it every month at least.
If you must, why not a cheaper lighter 2 stroke? Lots more of them around.
Your boat is easily towed by a good samaritan and can be paddled, too. That factor depends on where you boat, of course.
If it's available, calling sea tow once every 5 years, even paying full fare, is cheaper than a new 4 stroke.
Now, if you need it for trolling, the back-up feature is a freebie. If you already have the motor, or will be using it on a smaller boat too, it's a freebie.
