oil change and raw water impellar

[country_bumpkin]

Thanks for looking at this thread.

Probably could find a 100 threads that will answer my 2 questions, but here I go.

My 2nd year with a 1986 Imperial, 20ft. Mercruiser engine reads 488 (inline 4) and the outdrive reads 165 alpha one.

1. How the heck do you change the oil? I was successful but ended up covered from head to toe. Can you buy a pump? Drain out the transom?

2. The raw water impellar, where is it? In the outdrive?

I can get around a car engine, but this is proving to be a very new challenge.

Thanks again.

Signed,

The rookie

Your local marina/boat parts place will carry oil suckers for pulling it out the dipstick. Yes the raw water pump impeller is inside the outdrive. It mounts atop the lower unit.

Either pump it out the dipstick tube or you can buy a drain kit that goes inplace of the drain plug and had a hose that drains it out the transom drain hole, then you put a plug in it and leave it hooked up

thanks, out of the dipstick! cool.

and the drain kit sounds simple.

I pulled the plug hoping to direct the flow into a funnel and out the transom......uh..........well..............it didn't work very well.

and thanks for the info about the impellar.

I've had really good luck with a $15 pump that attaches to an electric drill. Iboats has them as does alot of hardware stores. Get some old garden hose, you need three male hose connectors, one for the top of the dipstick fitting and the other two for the drill pump, warm the engine and you'll be done in ten minutes. I've not had luck with a suction device as there are many hose to smaller hose adaptors that all leak to get from the large suction vessel to the small dipstick tube, the screw on type eliminates all that.

Don, the separator is finer than the little filter in the carb?

Thanks Don S.

But I don't see a link, I do see some related threads below.

Re: oil change and raw water impellar

One thing you need to understand about those pictures. They are all in the Mercruiser OEM Service manual #6 ........... Which just so happens to be online. Here's the link.

Can't help you with an engine manual, that's going to be ebay or Merc.
