Default Whats nessecary on a Yamaha F150 100 Hr Service?

Looking at the list, is things like new spark plugs necessary on a 100 hour service?

all oem oil and filter-yamahalube
oil change + filter
gear case oil
water pump impeller change
factory or clear bowl racor filters fuel water separators

is anything more than that necessary for a 100 hr service?

thanks

I've typically done waterpumps and sparkplugs about every 3 years or about 500 hrs. Not that I am recommending it. But it will make ya'll who change it at 100 hrs feel very safe. None of my waterpumps or sparkplugs were in bad shape when I changed them either.

Default water pump at 3 years/300 hours?

The reason for changing more often is not so much the impeller, but keeping the lower unit bolts from seizing. If you run in salt, I think waiting 3 years to drop the lower unit is asking for it.

Actual impeller life depends more a number of variables. Letting one sit for long periods of time, storage temperature flutuations, solids in the water you run in, etc. If you run regularly in clean water, it will go a long time. Long storage or cold climates cause the impeller to harden faster and sandy water will cause more rapid wear.

BTW, the manual says to inspect/replace every 1 year/200 hours. When in doubt, RTFM......

Also to add to the above..the dreaded impeller keyway that gets frozen in the driveshaft. I didn't get much of the maintenance history of my motors, but when I dropped the lower units, I had to work the bolts a little to get them out. Also, both keyways were frozen and had to be cut with a dremel to remove them. Andy at SIM has some really good priced kits for doing these Yamahas. He also has a thread on doing a lower unit service and a motor oil change.

plugs? glen says 20 hrs. mine were not done at 20 hour service, i dont believe the chart says it should of been done, maybe thats a verado thing...
how much plugs go for? where to shop for things like that? thinking about the racor see through bowls to see water/dirt... read they're worth it.
what about fuel filter on motor?

So Flo,

Here is the list from Yamaha in case you don't have it. http://www.simyamaha.com/category_s/1807.htm

We usually do water pumps every 200 hours or 2 years. Yamaha's recommendation is tighter then that.

I would do plugs at 100-150. The Yamaha's plugs are all that terribly expensive.

If you have a good 10 mic filter in the boat, you can do the engine filter every other 100. If you don't have a boat mounted 10 mic filter, add one.

Not sure what year F150 you have, otherwise I would send the link to your specific parts page on our site.

Andy

Soflo,

With the Racor, you will have to replace the element only after the initial bowl/element purchase, so there is only a $10 or so price difference between the replacement elements(Yamaha versus 3213 Racor). The clear bowl is reusable and the replacement elements come with bowl orings and base gaskets.

I don't think any one filters "better" then the other. The Yamaha is physically bigger and should last longer. I don't think lasting longer is as important since they should be changed on a hourly basis anyway.

The Racor biggest advantage is that you can see water if its present without removing the filter. With the Yamaha, you won't know unless you remove the element and drain it into something.

Andy
