I just purchased a 1974 Boston Whaler paired with a 70 Suzuki (4 stroke) and wanted to add a kicker. The reason for the kicker is simply as a back up plan in the event the 70hp goes out. I would like to have both engines (4 strokes) and was curious what would be the minimum hp I can get away with while limping back to the boat ramp. I was thinking 6hp, but I am really not sure. Thanks

Re: Good size kicker engine

lotsa variables in your decision....how far do you go, small lakes? open ocean? if you boat on relatively small lakes, a 6hp may do what you want, but otherwise, go with a 9.9 . jmo

Thanks nwcove, Also wanted to add the boat is 16'7. I am not even looking to get up and move, but rather just get back to the ramp. I was also thinking 9.9, but the price and weight are holding me back. I don't want my boat leaning to one side.

It can amaze you how little HP it takes to move a Boston Whaler 17, Permit. The PO of my Montauk fished salt and used a 2HP Evinrude. I used a Johnny 3HP, but my Suzi DF70 was so bulletproof I just took it off.

Since you want a 4 stroke I would recommend the OMC JohnnyRude (Suzi) 8HP from the late 90s. It is a very smooth twin and wouldn't drive you crazy with noise and vibration like the singles do. It is also pretty light for a 4 stroke. . .I seem to recall only about 70-80#. It wouldn't plane your Whaler, but it would get you pretty close to displacement speed.

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.

Re: Good size kicker engine

Would a larger size electric trolling motor maybe work. Serves a dual purpose.

probably but that depends on typical opposing current/winds, and you have a shorter battery life. Carrying an extra battery and keepnig it charged to use once every 5 years in case of breakdown is equally impractical to an OB. Unless you bought it for trolling.

Re: Good size kicker engine

Thanks for all the input, and it's a lot to think about. I have found a good deal on a Nissan 5hp, and i already have a trolling motor. My best approach will probably be to only take the kicker, when i am going through the inlet and stick to the trolling motor (electric) when playing in the bay.
