1985 Bayliner Ciera Impeller Location.

[blackgamen]

This may seem like a really silly question but my father recently had problems with his as in the title, 1985 Bayliner Ciera. He had been having problems with it last year, the engine was flooding quite a'lot, by the way the boat had been bought from the US a couple year's ago so he's somewhat of a novice Bayliner owner. Anyway, to try to maintain the engine he had a tune up done, spark plugs replaced, points, rotor button, condenser, distributor cap ect. A HUGE mistake one that has caused problems, mainly because he didn't realize how big a problem this could cause the engine was started with earmuffs on it while outside of the water. IT sounded great, but we believe it caused the impeller to burn up.
When removing the lower portion of the leg to replace the impeller it wasn't there, so the question is where is the impeller located on this model?
I believe most will know the engine is a OMC model.
The place where from many videos I've watched where the Impeller is housed in the lower portion of the leg and it's not there. I know they can be located in the upper leg, but how would this be done?
I apologize, I am personally not much of a mechanic, I'm just asking the question for him.

The 85 is a VOLVO!!
The waterpump is inside the engine compartment.
There should be numbers on the motor.
Pics of the motor,drive will help us determine what you have?

Volvo Penta Marine Engine Parts and Accessories Online Store - Volvo Penta Go there and find the motor you have.

Pictures would help identify which drive you have. If in fact it is an 85 omc unit, the impeller housing is located in the bottom of the upper unit.

How could running the engine using muffs cause the impeller to burn up?

I went out and took some pictures of the inside of the leg.

It didn't cause it, just don't think muffs work for this specific stern drive.

If anyone knows more go ahead and say
I didn't have that part worded right, so that was my bad.

Re: 1985 Bayliner Ciera Impeller Location.

Your drive is the later full mechanical stringer drive. Unless one happens to have the trunnion cap flush fitting, muffs are the only other way to supply water when running on the trailer. They are a PITA but quite sufficient to do the job.

You will have a much easier time of working on that drive if you remove it completely. You are putting a $5-700 shift cable in jeopardy working on it that way.

HI! This message actually helped a'lot. I was able to do some more research knowing the exact drive, we set up a work bench behind the boat to hold up the drive much better so no tension is on the shift cable.
The issue wasn't the impeller, the water pump drive shaft was in terrible shape. This whole unit was not maintained at all from looking at it, there is a'lot of build up and we're wondering if cleaning everything would be a good option, I've already started on it.

Cleaning up is always good. Saltwater always makes things worse. My Hydro-Mechanical is now 34 years old, with a lot of heavy skiing use, and has only been gone thru once. The water pump shaft was one of those items that got replaced. It was not a matter of maintenance but simply a characteristic of the breed. Idling is hardest on that shaft as there is no shock absorption with a solid steel coupler. Another area that need attention on an old boat is the intermediate drive shaft and coupler. They need to have lubrication and after many years, it dries out. There is an Oring in the coupler meant to hold grease in place but after so many years, you really need to pull the motor and re-lube it.

Also. IMHO the OMC impeller is not only bigger than the black anchor impellers, they last longer. Merc people will tell you that their impeller should be changed every couple of years. In clear lake water my impeller has only been changed once in 34 years and that was for general principals.
