Yamaha 30 HP Oil Seals

[Keith13]

I have a year 2000 30 ELHY Yamaha that is new and never been started. I have been thinking of changing the impeller, starting the motor to check it out and sell it.

My question is after all of this idle time should the lower unit's oil seals also be changed? Also can these seals be changed without complete disassmebly of the lower unit?

Thanks and Regards, Keith

I'd consider it a brand new motor...add some gas and run it....remember there is a 10 hour break-in procedure.....

I have seen many seals become stiff over time. The best thing to do would be a pressure check. About 10 psi should do it for a Yamaha, because they are built with the seal lips facing the same way on both seals. If it holds, no problem. Run it and sell it.

You do not need disassemble the whole unit, only pull the bearing carrier to change the prop seals.
