CONTINUOUSWAVE

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. The 2008 Boston Whaler boat was just as clean. I assume the fuel is still soaking into seals and gaskets ...

I appreciate [user upstateNY] getting back to [the forum and posting the details of the solution to his problem that revealed the cause was completely external to his engine and was in the external fuel system--jimh] I was having problems with [my 2007 90-HP four-stroke-power-cycle engine] losing po...

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...

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...

What was [the cause of] the problem?

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 for your reply! When I fire it up it runs great. It gets up on plane and were off. Then it bogs down. I take it back to idle and then It will get back up for 15 sec and then back down. The last time it will act like it wants to bog down but wont. I can power through it and it clears up. It se...

2007 Merc 90 hp efi 4 stroke with 100 hours on my montauk 170 has problem just leaving marina. Fires up and idles just fine. But after WOT 30-60 sec later it starts to bog down. Take it to idle then back up just fine... 30 sec later it bogs down. It does this 3-4 times then it runs the rest of the d...

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.

Has anyone had trouble with the fuel line kinking when the tank if pushed all the way under the seat? I have a 2008 montauk 170 and when replacing the line def noticed some memory where it entered the hull.

Thanks
