Re: Annual Maintenance $$
so i am curious on a brand new boat does one have to change the oil for out drive every year and also change the impeller , which is the prop, thats new to me, why do you have to change the prop every year, am i missing something
Outdrive lube should be changed annually, normally at the time you lay up for the winter. You always want to be on the lookout for water infiltration.
The impeller isn't the prop. The impeller is the rubber vane-type doohickie that sits in the water pump housing and pushes cooling water through the motor. Mercruiser Alpha drives have the pump in the leg of the drive.
As for the prop itself, you want to remove and replace that annually, too. Grease the shaft so the prop won't freeze to it from corrosion.
Read your outdrive manufacturer's owner's manual. It contains all the recommended maintenance.
