I plan to do the 100 hour service kit this fall, then do water pumps in the spring. Does that make sense? I bought my 2012 2660 CC this summer, and it looks as though the engines were *not* maintained at the end of last season (Engine hours show 165 since last maintenance). Since it's almost haulout season, I'm going to finish the season. I'll get them cleaned out/winterized, and take on the water pumps in the spring when the trend is warmer weather coming, not colder...
These are my first outboards and I love them, my past experience is with an I/O and I think I'll like these a lot more.
I'll be posting a dumb question on a new thread regarding shrink wrap in a new thread. Thanks in advance for any comments / suggestions here.

Yep, nothing wrong with that plan. Even with the low hours if those lowers haven't been dropped and pumps replaced in 8 yrs dont be surprised if it requires a bit more elbow grease this go around.

What's the normal life expectancy on the impellers? For my Mercruiser I/O it was every 2 years....

And grease everything up real good including the bolts holding the lower on and be sure to remove any corrosion on the shaft - a scotch bright pad works good for this and sand out any corrosion in the woodruff key hole real good and put grease in there and on the new key. Yamaha blue marine grease is the ticket.

I think the common wisdom is every 3 years whether they need it or not. Some might say it's overkill, but if you do it on a schedule like that, you're a lot less likely to have a pump problem that leaves you stranded, but also less likely to have a problem taking things apart, having stuff frozen etc.

I heard that the compression ring was a pain. Lucky for me, the f250 does not have that ring. You just slide the pump housing right up the shaft. Nice work bud. The compression ring I just cut them with a grinder carefully not to hit the shaft, their a real p.i.t.a.

My Master Yamaha mechanic recommends changing the impellers every other year/service, or about every 200 hours.

Well I don't run in any shallow water where I could pick up sand. I've gone 3 or 4 seasons 300 plus hrs. when I changed them they looked as good as the new ones.

With my first 2-stroke 150 HP Yamaha, I didn't know better and I hate to say how many years it was before I pulled the lower unit and changed the water pump. Even then, I can't say it looked bad!
Without having to squeeze pennies as much, I enjoy having the peace of mind that it is being maintained 'by the book' so I don't have to question it 30 miles offshore or somewhere loaded down with the family.
