Got it in today for a quick littlw test run.

Idle up to 3200 smooth. Above that (basically when secondarys open) busted up and misfiring. Open hatch. Water is on the bottom of sun pad and on dist cap and coil. Look in carb and see water. Dry all that. Same but alight improvement. Cruise at 3200 rpm (34mph gps) try again a few times and it has cleared up. Less than ecstatic it only ran 56mph at 5200rpm. Feels like it wants more wheel on it. Dropped back to cruise. Try again a few minutes later Misfire again. Gonna change plugs and check out cap/ rotor and run again monday. All in all I'm happy with it. Just for some reason felt it would be closer to 60.

It takes alot of HP to make these birds fly.
My buddies 242 with the hook in the hull, 300hp 454, runs 52mph.
My 242 with 420hp, hook removed, ran 62mph.
My 242 with 572hp, hook removed, now runs 73mph.

Mine should be 420-425 hp I was really hoping for 60. I didn't hold it down long but I know it can spin more prop. I feel it could do 60 with the right prop.

Any idea why the bottom of the sunpad, dizzy, and rear of carb would be wet after running a few mins? I would think it was dry it hasn't been wet in months

Looked up the part number on the prop. It is a mercury revolution 14 5/8 x 19 4 blade. What would you guys think to be the next size up that wouldn't just kill it?

Hunter, any water accumulation in bilge? Water IN the carb?

Water in carb was from sucking through air filter. Very little just saw it beading on carb butterfly. Yes there was some in the bilge I pumped out for about 15-20 seconds when using bilge pump. I had it idling while tied up and looked all around and nothing was dripping. I guess I'll have to look harder.

Gary I wonder if this might be that the hose for the speedo is broken and spraying in the bilge while running...?

That may be it. Do you have a GoPro?

You could remove the hose where it connects to the lower portion of outdrive.

Without knowing the specs of your motor, its hard to tell if a prop change will help you. Putting a taller prop will lower rpms, negating the increase in pitch.
