No worries

Honda's are very reliable motors and you need not worry too much. I would check the thermostat area if the motor has seen salt, as you can get a build up of crystallized salt deposits there, and it can restrict the cooling water flow. A spare set of plugs is fine, but not much good without the tools to change them. The plug size is 18mm and not in most tool kits, and hard/impossible to get with a wrench. If you have the Honda tool kit, it comes with this wrench and a starter rope should yours fail. There are also cotter pins and shear pins in a rubber holder attached to the motor opposite the tiller.
I don't know the size of your boat, but my 33 year old Honda 7.5 starts first pull, and pushes my boat at hull speed with almost zero throttle. Fuel use is nil at hull speed.

tommays I only went to OMC school for a 1000 hours BUT it is still a water pump and it is usally BEST to get the full kit due wear in the impeller housing

And at 8Hp it may have a thermostat but you will have to look in that motors service manual which is also a good thing to have

You should also change the lower unit oil looking for any sign of water

timebandit Because you don't know the history of the motor I would recommend --

Change the impeller and take a spare one with gaskets.

Change the plugs and take a spare set.

Change the oil in the engine and lower end.

Spare starting rope.

Check the oil often in the begining for usage. I like to put the oil in one of those shampoo bottles that have the little flip open spouts. I think that engine only holds about a quart of oil total so add easy.

Vasco BlueWMD,

That's a nice trip. I would not be too concerned regarding the condition of the motor. There's a stop every thirty miles or so where you can get assistance if you really need it. Good luck.

sailingdog Tommays-

This is an 8 HP outboard motor we're talking about...and they usually don't have a separate water pump that can be replaced... impeller and gaskets, yes, but no separate water pump.

BlueWaterMD The boat is new to me. I live in Tampa, and just bought the boat in the Cape Canaveral area (east coast). My only experience with the boat from the sea trial last week. Late november I am going to take it from cape canaveral down the ICW to Stuart, then across the state via the okeechobee waterway, and then up the west coast to Tampa (about 400 miles). I have had power boats before, and never even worried about the engine, but that was because I was familiar with them. This one is completely new to me. I will be on the boat the next 2 weekends trying to get things in order, before my trip.

Vasco BlueWMD,

If it's running fine leave it alone. Have you had this boat long? What's your history with the motor? You sound like it's all new to you. Now if it is all new to you, you do have the most important thing -- towing insurance. Good luck on your cruise. Oh, one little thing, take some engine oil with you to top up if it gets a bit low and that little green light goes out.

xort Is this a pull start motor? If so, then a spare pull cord and the tools/knowledge for replacing it.

Banshi "Umm, you're supposed to be cruising, not running a floating outboard repair shop"

True but on mine, which is older, it is a rubber belt easily changed out if it breaks. Sort of like a fan belt on your car.
