Yes I am concidering the Merc 90 to replace the 80 Yam I have. Nothing wrong with the Yam, but it is quite old and wouldn't feel 100% happy without an Aux outboard strapped to the transom, which is exactly what I've been doing.

I like the Idea that I'll have a much newer outboard and wouldn't need an Aux.

The Yam weighs 135kg according to my manual and from what I can make out the Merc weighs in at 175kg, so is 40kg going to make that much difference! Have to remember that the Auxillary won't be aboard and neither the fuel tank for it. I will end up with a heavier steering I suppose and I will stick to good old cable type untill it needs replacing.

I am buying purly on the fact it's a newer outboard than I have currently and If I get better fuel consumption, great! Should also be able to cruise around the harbours better that with the Yam as it never felt comfortable on low revs.

Budget wise it's tight and I guess there's always a risk of buying the wrong outboard for your boat combo. But we are all in the same boat when buying a hull/engine outfit.

Incidently, didn't Daniel have a 130 Yam V4 on the back of his BWM Deepsea 18, that must have weighed in pretty heavy.

Thanks DJL, I'll have a look.

Andy....Am i correct in thinking your intending to switch from 2 stroke to 4

I changed my engine back in September from 2 -4 stroke and wish i'd done it ages ago, the 4 stroke is brilliant, its efficent and you can have a conversation with others without having to shout at each other, i'm now considering fitting a sterio as its so quiet on the boat

I cant vouch for the Mercs but will say people seem to have trouble obtaining parts and parts on order seem to take ages to arrive, Yamaha on the other hand seem to have got the dealer networks right, parts seem easier to obtain if your in a hurry.

Good luck with whatever you go for

Richard

Yes Richard, you are right.

Rat, there's a clue in the first line of his penultimate post.

Daniel did have a 130 V4 on his BWM. Weight 167kg, with more power snap and lower centre of gravity than a Merc 4 stroke of equivalent power.

Weight outside of the transom is critical to the balance/handling of a boat(more so in rough seas).

Hightower,Come and have a play in my boat if you like(after 7/1),the yam is slightly lighter then the merc(167kg dry),and the weight on the back of my 5.7 (which is quite narrow but the tubes extend behind the transom a fair way)seems fine.
The yamahas seem a bit more expensive but it may be useful for you to try it.

ive just changed my mariner 40hp two stroke to the mercury 50hp which is a jump of over 300cc and a new cylinder to go with the other two and i would say thats the biggest two stroke i could afford to run apart from carrying fuel

as bilge rat said the parts are a real pain i waited two weeks for a trim tab which should be a service part as it an anode as well the bolt that fitted it took two weeks back order which can be a pain

my wish list would be four stroke but the most important would be EFi
no carbs as most of the running probs on this forum are down to carbs it seems. i think the mecury and mariner brands are very good and i think barrus
is down your way which are the importers you could go direct to pick up parts

good luck

dan

Timboli, thanks for the offer. Might take you up on that trip! I am going to buy, but cannot get my hands on it untill end of Jan when it is replaced by a 150hp Optimax.

Daniel, I am aware that there is some supply and demand probs with Marina/Mercury, but customers always seem to get bits in the end. This motor has carbs and not the more desirable EFI.
