Looking for a bad Mercury Black Max 150,175,200. Need the style with clamshell cowling but I do not need the cowling. Don't need a rebuildable powerhead. Could also use the power trim motor assembly....

trim motor in the boat.
maybe mine is not an XR6 and that could be my cowl problem! Mine is an oil injected Black Max 200 and the front cover has no place for the latch to catch on the motor, looks like maybe a frame crosspiece missing below the airbox? can't recall what my old 150 looked like.

yours is pre '83 model with a single cylinder till n trim.. tha cowls won't even start ta fit tha XR6.. clam shells need a bracket that bolts to tha air box in front and a bracket that bolts to tha divider plate in tha back..... tha below covers most of all tha parts on yours.. is for tha '81-'83.. disregard tha trim dia. thats next to tha oil tank and acc block. that dia is for newer 3 ram stuff.....

thanks, this one is a 81 model, cowls on it work fine. Trying to find a broken motor to scavenge parts from like the front bracket that the front cover latches to and the studs/nuts that hold the airbox on.. The front cover is rigged right now but I am not ready to pay 130 for just the new front bracket.
Thanks for the diagram/part numbers, they will help to locate used parts if I don't find a donor motor....

you will need tha serial no.... it could be one of three.. think tha 99424 is gonna be for tha 200.. its different from tha 2.0 150.. tha picture is generic for all three.

I need the one for the 200. My serial # doesn't come up on that site but I checked thru Mercury and it is a 1981 200 ELPT 6009440

put a "0" (zero) in front of tha number..... merc added a 0 ta all serial numbers a few years back..... don't know who ya talked to at mercury but every site i have access to including MercNet shows a 2.0 150.......

does your air box have what looks like plastic pipes coming from both sides at an angle? or is it rectangular with no visible openings except holes straight out tha back?

cool, thanks. Could be someone put a 200 cowling/divider on it or changed the powerhead although it was running a 25 Trophy on the 22' boat. Luckily I bought it for the boat and trailer and have a 2003 200 EFI to put on it. Just looking to check this motor out before I swap them out.
Still looking for a parts motor, no telling what else may be needed Also a trim motor/pump...
