Outboard Spare Parts
In preparing for a week long cruise on the ICW what do you think would be the most important spare engine parts to carry? I can handle some basic repairs, but am not about to try to rebuild a engine on the water. Also, keep in mind, I do have towing insurance, and for big things would probably rather just getting the tow to the nearest marine. If it helps, the engine is a 2002 Honda 8hp four stroke outboard.

Shear pins, spark plugs, impellers. These are the things that I can think of, but I am sure there are more.

A couple of spare plugs should do you. Being a 4 stroke you probably don't even need them.

I'd second carrying shear pins, spark plugs, extra impellers as pointed out above. I'd also recommend carrying spare fuel filters and a spare prop.

BTW, you do have a water/fuel separating type filter in the fuel line, right???
If not, add one ASAP. Getting water into the fuel and into the engine is one of the biggest sources of problems on outboards. A fuel/water separator is a simple way to prevent these problems.

Do outboards still have shear pins?? Both mine have rubber hubs on the props and when you "spin a prop" you have to get a new prop. But if he's a sailboat there's little likelihood of spinning a prop.

My 3.5 HP Tohatsu has a shear pin. Don't know about my 20 HP Honda, but I use a composite prop on it that tends to shear blades before the shear pin would break, if it has one. :)

Timing belt?

Umm, you're supposed to be cruising, not running a floating outboard repair shop. :)

That's true. It's only one week and he does have towing insurance. That's why I said at the most a couple of plugs. Have you ever tried to replace an impeller in an outboard?

Thanks for the replies everyone. Also, what are your opinions on having a marine mechanic check out/ tune up the motor? I have heard mixed feelings on this. The motor seems to run just fine, but I am moving the boat close to 400 miles, and a majority of that is going to be motoring. I don't want to break down along the way. I don't have many records from the prior owner, and want everything to be in top shape before my trip. I would do most of it myself, but just don't have the time, especially considering the boat is 3 hours away.
