The Mercury has 20 extra ponies!

You should have haggled the Merc dealer up a bit for peace of mind

The sad thing is by the sounds of it I think your right! Doh

mercury F 150 is cheaper because has 20% parts/components less than nearest competitor....ha ha

My friend has this mercury F 150 on bombard 7,5 m, he is doing taxi transfers. Engine is old "2 seasons", 700 hrs +, he said min 700 hrs but for sure much more - he don't even know! He did some maintenance, but never in regular intervals!

I asked him how is he satisfied with engine, he said very good. This opinion is enough for me. But maybe his engine is extraordinary and because of this I wanted opinion from other people but as I see nobody has to say any thing against this engine...

When this guy is saying "I did some maintenance" this does not mean he did. Once he was saying he is not satisfied with yamaha f60, on engine is only 400 hrs, consuming oil...bla bla... later on conclusion was he did first oil change on 400 hrs, so he bayed a new engine and first oil change on 400 hrs!

The 10% rule, as an owner of a Suzuki 140hp you might regret asking that question.

Serviced a 150 today. A pleasure to work on. Looking forward to the rest of the range that will follow.

From what I've read the Mercury is a 3 litre 4 cylinder.
Other 150s are lower displacement.

The Mercury is a single camshaft with only 2 valves per cylinder.
Other 150s are twin camshafts with 4 claves per cylinder - hence more moving parts claim.

Looks like the Mercury makes its power by sheer displacement rather than high revs and multi valve heads. This "should" also give it good low down torque.

"There ain't no replacement for displacement" to coin a phrase from the US of A!
