Mariner 75hp - 05/24/17 01:49 AM
It's a 95 mariner 75, rebuilt the fuel pump /carbs 4 months ago. Ran great until Sunday, now it has a hard time getting on plane sometimes, it will run fine to one spot, next not want to get on plane. Could it be that fuel pump again?

Sounds like a ignition problem....OPTI

Switchbox? Or? The motor idles great, it's once you put it under a load.

Depending on the ignition system if it the old ADI ignition system it could be the switch box but that would effect the way it ran at all rpms. Could be also trigger it really hard to say. If it is the new style system with CDM this system does not have a switch box. Could be a bad CDM ....OPTI

Cleaned carbs/put new spark plugs. It's ran great so far,
