The boat currently has 125 hours and is going into winter storage in a few weeks. I plan on performing the 100hr services ones the boat is out of the water for the winter, will the extra hours without service cause damage to my boat?
 
Make sure you change the water pump impeller! The book says its good for 300 hours, no way it will last that long.

At 100 hours, my mechanic convinced me to change mine. He was right, it was all chewed up. I replace mine every year regardless of hours.

Other then the obvious oil change, why do a 'tune-up' if the engine is running well? And why the expense of an impeller change for the same reason? Is this just Marine Max/Newport Boats staying in business???

I think it is called routine maintenance, much easier to change the impeller on land in the shop then out on the water if/when it fails.:huh:
 
so every 100 hrs whetever it needs it or not ?
 
cheaper than a haul and block in the middle of summer.
 
good advise. I'm going to do it ASAP. The impeller in the genny failed last weekend, luckily had the part and a buddy replaced it. all good. I'm sure the mercs will take more time to replace!
 
Since I was recently stranded due to shot IAC valve, I am adding a preventative replacement of that part along with the impeller every 200 hours. The IAC part costs about $100.
 
don't forget the little AIC filter in the throttle body. If that gets clogged, then the AIC doesn't work so great.

How would you know if the impeller is okay or not without pulling it apart? And if you pull it apart you might as well replace it. In Florida we boat in shallow water so the threat of shells and sand is ever present. In addition the rubber starts to get memory after 100 hours. So while the boys are pulling the drive it's a good time to change out the impeller. Also change the fuel filter.
 
Did you put all 100 hrs on this season? Was the oil new when the boat hit the water this year? I've seen people use their equipment for years without service because they have not hit the mileage for the first service interval.
 
No. I bought it used almost two years ago. I have put about 100 hours on her and just recently had the oil changed. She's running perrrrfect so youy know..."if it aint broke..." but after the impeller issue with the genny, I got thinkling. Anyway, I'll have my guy replace them on the engine (once I find who sells the impellers for them,!) and hold off on the 'tune-up' untill I feel shes running rough.

The whole point of preventive maintenance is to avoid ever having it run rough. If you wait until it runs rough you will likely have more problems than a simple tune up.

I get regular tune ups on my cars BEFORE they ever run rough. Same thing with a boat.

IMO, the oil change is tops on the list. With EFI, going a little beyond the 100 hrs is nothing to worry about. There are no carbs, no points, no distributor/cap. As long as you keep your fluids up I think you are fine.
