4400 MB Black Death

When I put it in gear for a couple of seconds water started spraying out of the air vent where the drive belt is. So I turned it off, unplugged the drain plug on the bottom of the motor and about a 1/4 cup of fresh rain water came out (since I run in brackish water I tasted it,,, it was fresh) I have a cover for this motor,, it doesn't cover the drive belt case but it does cover the main motor. Any suggestions to this weird ass problem? _________________ Lead, Follow or Get The Hell Out Of The Way!!!! 1754 Gator Trax Hybrid, Hunt Deck ,with MB 4400 Black Death HDR, Duck Slaying, Mud Slingin Machine!!!

It may be damaged and letting water in. Run a hose on it and see if you get water in the housing. Or remove the cover and shine a flashlight around the back of the housing and see if you see light showing. Something simple i'm sure. _________________ 1854 Prodigy Open HDR/Stage 3 mods Prodigy Boats Pro Staff BPS Swamp Staff Member Blackwater Marine LLC.

Its where the motion base mounts to the block. There are slots machined into the belt housing to allow the the housing to move up or down to tighten or loosen the belt. I think .005 is a bit tight. I have roller rockers, cam and heads and set mine @ .006-.007. I realize its only .001 difference but, its probably closer to .002 depending on your feel. Every motor is different. Yesterday had mine out for several hours and it barely made it one revolution and it fired right up every time. Sometimes it rolls over for a few seconds and longer when its cold af outside. Don't over think it, its still a lawn mower engine. _________________ 1854 Prodigy Open HDR/Stage 3 mods Prodigy Boats Pro Staff BPS Swamp Staff Member Blackwater Marine LLC.

You were correct on BOTH cases.... I took the case off and sure enough,,, after setting the tension on my drive belt at the 10hr. mark,,, I forgot to re-seal the bolts back there...... that was the leak,,,, as for the valves... I set them to a snug .006 and she starts up with little to no hesitation at all... Thanks brother....
