Location: Madison, WI | How often do you guys get a spring tune up on your motor? I've been talking to a few shops in town looks like; changing the plugs, fliter and checking the timing seems pretty routine, for $150. I've had my boat/motor for the past 2yrs and haven't had it in the shop. Is there anything else that I should be looking to get done before the boat hits the water? |

Location: Elk River, Minnesota | I am still using a 2 stroke for my big motor and after burning all the fogging oil out, I change the plugs. This year a new fuel filter and impeller at some point (been 3 years on those for my motor). Couple of adjustments to linkages and/or grease pivot points, and it is good to go.
If you have a 4 stroke, it would be new oil with filter, and new plugs. Given you have changed the lower unit fluid in the fall, that should be all it takes besides grease to times that need it.
Plugs for many motors are pretty inexpensive, so I replace them yearly as preventative maintenance.

| Exactly what these guys said! Wanted to add that it is way easier to do these things on your own unless your time is worth much much more of course!! However, I choose to do the upkeep on my boat by myself or anything I have the power to do just because if you are on the water and get in a jam it is kind of nice to have an idea of what may be wrong and able to do an on the water fix! |

Location: Madison, WI | I'm all about the plugs, grease, and seafoam! That's my style of a spring tune up (and much more in my price range). Is the impeller a consumer changable piece? I have a 2004 125 2 stroke merc. |

Location: Elk River, Minnesota | Hiya,
If you can handle a wrench, the impeller change is not very hard at all. The usual hang-up that some people have is unhooking the shift linkage on some motors. From what I recall, many of the OMC products and possibly some merc products had a screw that you had to remove on the underside of the engine in order for the lower unit to come out. If that is not removed, the lower unit will drop about an inch and hang up. That may have changed now, depending on age and style of motor. I know when I did mine last (2008) the lower unit bolts come out, and the shift linkage was a splined shaft which rotated when to put into gear. So...there was not the issue with shift linkage.
Overall it is not a hard project, but if it is your first time doing it, a second set of eyes and hands are really helpful. If you lived in the Twin cities, I'd help out...

Location: Richland Center, WI. | I have a 2004 Merc 90hp 4 stroke. Should be similar to what you have as far as impeller change. Posted on here and was given a link that shows how to change it. I will try to attach it here.
Good luck, Ken
