|this is my second season for the boat...the dealer has recommended a impellor change....is it really necessary right now??|
|Consider the difference between maintenance and repair. |
Changing your impeller is maintenance, itís recommended annually. Replacing an engine that overheated because the impeller failed is repair. Maintenance happens more or less on your schedule, repair happens when it wants to which according to Murphy is most likely to happen at the worst time.
Keep the old impeller as an emergency spare.
|Better safe than sorry. It is only a $35 part. |
Do it and save your self the long term Potential Problems. It should only be 15 minutes of labor so dont let them screw you there. I can change mine in less than 15 minutes and I am no Marine Mechanic.
|Yeah you should definately do it. My Dads Mstercraft with the LT1 corvette engine goes through them like crazy. We keep a spare in the boat at all times and have changed it on the fly in less than 5 minutes. Like the others have said its a good fix plus a lot easier than fishing broken fins out of your block and thermostat. Use a little binding lube to get it in there easier.|
|I change mine every year. The old one always looks in good shape, but to me replacing it when I summerize just means no lost time on the water.|
|I've always done mine annually but am considering relaxing that just because I fight to get just 50 hours per year. |
Just for fun, check out our v-drive and d-drive maintenance docs:
|I blew one last year. Ruined a trip to the lake. Needless to say, I'll be changing mine each season now. I recommend it, it's really scary to watch your baby overheat|
|I bought my boat late in the summer last year and was only able to put 20 hrs on it. I did the 20 hr service and a winterizing, should I have the impellor changed so soon or should I be alright? I do not beach the boat so I have not sucked up any debris such as sand or rock's.When I asked the dealership that serviced it they said I should be alright and not worry about it so soon.|
|Rob, No experience with Supremes, but if it sits in there dry all winter and starts to stick to the walls it might tear itself up on first start. We replace ours annually after a failure after 1 1/2 seasons on a MC 210. I'd pull the old one, grease it and the bore up for the winter and save the old one as a spare.|
