Mercruiser will not work without a lot of revs

Re: Mercruiser will not work without a lot of revs

Oh, and the rev counter doesn't work. So that's making it a tad more difficult.

:facepalm: Have a look at one of these. Good price, lots of features...

Re: Mercruiser will not work without a lot of revs

Thanks Chris, looks a handy bit of kit. Before I get this though, would it be that I'm just over choking maybe? I have moved the choke to 1 notch right of centre as well as adjusting the needle and screw. Maybe (I'm hoping!), that just a bit of fine tuning will sort her out. A bit more revs with the screw more against the cam? Unscrew the needle a tad more even? Now that I have her ticking over nice, the opposite of before.....was dying at low revs...now dying at high....:facepalm: it must be something simple? Almost going on my first trip, so close I can smell it. Any more advice would be utterly superb.:joyous: Also, what would be the best revs to knock her into gear without damage? Minimum or maximum?

What are the revs meant to be set up at for
:- idle

:- reverse engaged gear

Thanks again mate.

Re: Mercruiser will not work without a lot of revs

The only spec is for idle in forward gear, 'unhindered'. In other words, out on the water not tied to a jetty or anything...

For your engine, 700 rpm....

Hey @Emaraldsnake sorry to revive this oldie. I was looking for my post of the same nature and came across yours. Did you ever figure this out? I have the same issue, and have taken the same steps to fix. Walked away years ago and am back to figure this out!
