I've got a small shop where I generally purchase my Honda engine supplies, but I always feel like I'm paying about 2X the normally high price for Honda parts.

Anybody have a good source for Honda oil filters, fuel filters, spark plugs, rubber hoses, impellers, O-rings, carb rebuild kits ... All the stuff you need to replace regularly, but I just don't want to end up paying $40 for a $10 part.

And by the way - the Honda started on 1 pull this spring. I was completely amazed by it. It idles high, medium and low. Fantastic engine!

So if water is streaming out of the cooling water port, is that a good indication that the impeller is still good for another season? I've got the shop manual and by the looks of things, this is not an easy part to replace.

At least you can use any brand of sparkplug Just checked, Fram makes oil filters for Honda outboards and probably fuel filters. Everything else on your list, other than possibly an an occasional impeller, is an uncommon event.

My Honda 8 did not have an oil filter. Are you talking about the fuel filter? I bought my Honda spark plugs at a Honda motorcycle shop. I used an after-market fuel filter made for a VW air cooled engine.

Joe - was your Honda a 2 stroke or 4 stroke? When you mix oil and gas, you generally don't use crankcase oil or a filter. Dave, I'll try looking for the Fram parts online.

A friend of mine says he changes the water pump impeller every year on his chevy V-8 (stinkpot) because it loses its flex and efficiency over the winter. I've never heard of that practice. In his case, it's right on the front of the engine and easy to swap out.

Does he change the water hoses too? That argument suggests that all flexible rubber must dry out over the winter and be replaced. I have never replaced an impeller in an outboard except in a restoration, and I've kept some for a pretty long time. Something may happen that you have to, but as long as there is a steady stream of water outflow it is a non worry. I've also heard it suggested that you should carry a spare, but hanging over the stern changing an impeller sounds a little too risky to me. Put up some sail or call Towboat/US if the impeller fails. I don't necessarily replace sparkplugs every year in 4 stroke engines either, I check them visually and for gap and usually replace them when they need it or every couple of years. We all do many thing because that is the way it has been done or some myth has been handed down long enough to assigned truth, but a clean burning 4 stroke is not the same animal as the ancient 16:1 mix 2 stroke that gave rise to some practices.

The reason they suggest changing the impeller every year is that the rubber vanes will take a 'set' over the winter. I usually pull the cord every now and then over the winter to spin the impeller. You also have to remember that we don't put as many hours on our motors per year as a power boat does. Also if you beach the boat and suck up a lot of sand, Then I would change it. If the tel-tail has a good strong stream coming out yearly change outs aren't necessary. When I had the power boat I changed it every 2 years but that would be around 200 hrs. run time.

Doin' the math in my head, if I sail every weekend from May to Oct, that's 24 weekends - I don't. If I use the engine every time I enter or leave the river, that's 48 hours in a season - sometimes I can sail or grab a favorable current. If I motor sail ten times at about 20 miles (4 hours each), that 40 more hours. So in a season that would be about 100 hours.
