New Motor

[CJ Extrom]

Hey,great site. I am a new member so here is my first question. I just installed a new merc 90 on my boat,it

runs very cold and misses a lot. Dealer says 100-1 in the

tank book says 50-1, did 50-1 and motor will not idle now

I have burned about 10 gals out 20 in the tank. The plugs

drip in oil,but it seems to great above 3500 rpm on the lake

I am very mechanical inclined any help would be appreciated.

It did blow the main 20amp fuse when i first installed it.

Thank's in advance.

Dealer is right the motor is oil injected 100-1 in tank plus the injected part of the motor =ddl.oil add more gas to lessen the oil in the tank it will take time just burn it out.
