Guys

I have a 1995 Mariah Z220 with the 5.7 350 EFI. Whats the best weight and oil to run in the boat. The boat has about 450 hours on it. Is there any other maintence I should do other than change the lower unit fluid?

Change the impeller. It needs replacement at least every two years. I do mine every year because I never want to hear the temp warning buzzer AGAIN!

How hard is it to change the impeller? Is there any instructions online you have seen for the change of it?

It's not that hard. You don't state your drive type, but if it's an alpha 1 here is a good online reference:

As for oil, I just run the recommended Quicksilver 25w40.
