    Prop Question

    I have a Quicksilver Laser II 24P 3 blade SS prop with a 115 Merc. It over-revs on planing out and I noticed that the prop has rectangular slots at the front of the prop for extra exhaust gas, I reckon.

    Idle problem with 70hp Johnson

    I have an 88' 70hp johnson that has a regular fuel pump. At idle it sounds like it is starving for gas and when I try to accelerate it is very slow and never really gets wound up. If I hit the choke with it is running it will smooth up for a couple of seconds until it begins to flood. I have...

    Merc 115

    I am looking at a used boat with a 93' 115 Mercury. I have owned several Johnson/Evin. outboards with great success but have never owned a Merc. I was talking with a guy who said that the Merc only used the bottom two carbs. at low rpm and that it affected the hole shot of those motors. Does...
