Merc 75 to Merc 90

Hi Guys, following my disastrous trip out on the 2nd of Jan, (see earlier posts) I have decided not to repair my engine and to buy a new one. Well new to me. It will be a 2001 Merc 90hp.

I intend to take the old engine off the RIB and then drag the boat to the new engine and hopefully attach the new engine. What I need to know, and sorry if this is a simple question, will the transom bolts line up, or is there a difference between engines?

The original engine is approx 20 years old ans is now for sale spairs or repair. I'll get it on Ebay as soon as I get time to take photos of it.

Marvellous, that will make life a lot easier. Thanks.

I assume I can re use the transom bolts off the engine I'm buying, or use the ones that are off my original engine? Or am I likely to find they are bigger?

Sorry for all the questions, its just that I'm in Oldham, the engine I'm going for is in Oban, so I really don't want to drag my RIB all the way there to then find out I can't mount it over the weekend and have to come back without it.

Should just be a simple case of taking the old one off and bolting the new one on.

What sort of car do you have? Have you got a little trailer the engine would go in? Given the distance I would be tempted to put the engine in the back of the car (if big enough/suitable) or bring it back on a trailer.

Peugeot 406, can't see it fitting in that. I'm intending to drive up with RIB on the 27th March, get the Merc 90 attached on the Saturday, and then if I can get all the rest, Throttle, electrics sorted small sea trail in Oban Sunday morning, and then drag it back Sunday evening.

That's the plan, if all I manage to do is get it attached to the transom securely tho, I'll settle for that.

Hi Neil

Engine bolts and transom holes will be the same. Control box fittings and control cables should also be the same. If yours are ok, All that you need to do is swap the engine over.
I have a 90 merc available if any thing goes wrong with the other one that you have lined up. here . 1,450

Thanks Ian, I've got the one I'm after for 1500 with controls and guages, (don't know what guages) so its neck and neck really, but I've promised on the other. Fingers crossed, all will be well and it will be a good runner, failing that I will be contacting you for sure.
