Re: reliability question

reliability is all based on how it was taken care of before you owned it.

BUT typically Id say the 3.0 is a very reliably Mercruser motor thats why they still make it.

Its a hard working motor and does really good on gas. I had on in an 84 webbcraft and it ran like crazy. Just take care of it and it will take care of you.

Thanks bayliner and happy boating was just curious im new to IO so i will get manual also so i can do the mainteniance as required boating is best when u dont save gas by being towed

Re: reliability question

I agree. My last boat got toed in quite often it was the time between getting help that used to stink.

I would change the water pump implellar in the outdrive if you dont know how old it is, If you have had outboards Im sure you are well familure with this procedure.

DITO to what bayliner said!

Bigest problem I have seen with them is the distibutors ware out.
check it out with a good dwell meter, dwell should be steady not jump around if it moves around replace the dist.

LOL, I have a 60 Johnson and 90% of my boating is at idle speed. The nice thing about the Mercruisers rough idle, is that it can be fixed, the Johnsons can't be.

Re: reliability question

lol

Why am I not so surprised to learn Don still has an old Johnson, could it be the same reason I have an old belt driven magneto J85?

Cause we can and refuse to part with an old horse as long as we can keep it alive and running well.
