I bought the boat and engine used. The engine is 2007 Mercury 90 FOURSTROKE EFI--yes, EFI model. For an engine that is 11-years-old, it has very little running time hours. It's in perfect shape.

Re: 2007 Merc 90 hp efi 4 Stoke looses power then clears up.
I'm not sure but as you did most of the fuel supply (with pump exception) it might be one of the coil-packs. I believe that that there was a recall on them for those years on the medium HP size Mercury 4-strokes. My 60HP was doing the same thing and after taking it to a certified Mercury dealer the...

Re: 2008 Montauk 170 Transom support... "transom saver device"
I updated my post with a little more description. A transom saver is a device that adds extra support to the motor while trailering. It helps keep the motor from bouncing hard over bumps while trailering. Some attach from the lower unit down to the rear cross member of the trailer...Some just add su...

2008 Montauk 170 Transom Support Using "transom saver device"
Should I use some sort of "transom saver" for my 2008 170 Montauk with a Mercury 90 FOURSTROKE? You know the different devices you can support your motor from the trailer. Please share your reasons why or why not.
Thanks!
Thanks!

Re: 90-HP Engine Falls Flat at Full Throttle
I have a similar problem with a 2007 four-stroke-power-cycle electric fuel injection 90-HP, except [the problem] just does occurs at start up. It occurs about three times then clears up.
Any ideas?
I changed fuel line and filters.
