Mercury or Mariner

sburt10 · 24 October 2011, 22:27

Ok, a mate bought a new rib, second hand but was never used.

The rig was all set up but never made it into the water, he bought the boat and someone else bought the engine (before he knew about it)

It had a new 90 Mariner on it and all the clocks are in the console.

Can anyone tell me if he puts a 90 Mercury on it will all of the holes in the transom line up with the bracket and will all the clocks work without changing them out ?

Also, stupid question, whats the difference between Merc and Marniner these days ??

Cheers
Stephen

Nothing they are exactly the same engines.

Mariner seem aimed more at commercial and Mercury at leisure.

Yes they are spelt different!!

Other than that they are one of the same. Everything would be interchangeable.

You will find most other brands have the same transom holes too, unless your changing down/up massively on the HP

Hi CJL, so same engines, ok, so everything should be compatible ?

Thanks for the help guys.

If he went for an Evinrude would the quicksilver clocks work with it or would he have to change them for the evinrude ones, if so are the sizes pretty standard ?

They would need ETEC gauges. Most have a standard diameter so the holes should pretty much match to a point. It's the connections which differ

The holes on the transom should line up tho'......

It;s moments like this that an oldschool 2- stroke comes into it;s own - all the gauges are analougue, so they are usually cross brand compatible!

It does depend on the age too. Early Mariners were made at the sanshin factory who also made yam's. So the early mariners are Yamaha based.

early mariners up to and inc 40hp, plus the two cylinder 55, were yams. Above that they were mercs.
Back in the old two stroke days with our boat fishing club motto
"any engine as long as its a Yamaha"
or " are you goin out fishin tonite...oh sorry I forgot you've got a mercury, you'll be at home mending it!"
Things have thankfully improved greatly.

True but I don't recall Yamaha built any Mariner badged 90's, can you ? I thought the biggest were 55/60 models.

been there done that. My 40hp mariner was identical to m'mates 40yam...except for paint job, hood, fuel tank and tank end connector..oh and the alleged 100:1 oil ratio for the yam and 50:1 for the mariner. In practise we ran both at somewhere around a lean 50:1. The wiring loom in the mariner had yamaha branded bits in it. The only things that ever went wrong with it were the merc bits! The merc tank end fuel connector fell to pieces at sea and required the fiddly bits finding in the drain well. The suction pipe fell off inside the tank in the middle of a busy shipping lane and was fixed at sea with a piece of the poly tubing we used as a conduit for the boats wiring. Couldn't believe that the internal tank suction pipe was simply a push fit with no securing clip.
