    MCM 165 L6 replacing 140

    How much longer is the L6 than the L4? I have an opportunity to buy a 165 with the drive for $450. Is it Worth it even if it needs rebuilding? Second, does anyone have a dimension for transom to front mount distance so I can see if it will fit? It's quite a drive just to get the dimensions then...

    I have the prestolite high volume low pressure pump. It has the manual release valve on the bottom and 2 lines. 1) What is the real part number for this and what part number for the cap and brushes? 2) If I buy an oildyne unit, will it plug and play or will it need to be adapted? 3) Different...

    3.0-2.5 alpha1 -R/MR swaps

    I have an 82 Galaxy that used to have a 120 in it. When I rebuilt the transom I put a 140 from an 85 Renken in it with the complete works in and out. The lowers on both are good. The 3.0 had a craked block under the intake but runs good. It has been about 60 - 70 hours now ands the lifters...

    Placement of bunkers on trailer

    I have an 85 Galaxy 180 with the 140 merc I/O. What would be the proper support for this on the trailer? The stringers are on ribs closest to the keel. The next set does not have any stringers. Should I move the bunks to the flat on the rib or leave it between the rib without stringer and rib...

    Lowrance X-51 PRO speed sensor?

    What is the difference between the x51 and the x51 pro? Can the speed sensor for the x58 and x51 be used on the pro? I see nothing in the online manual that indicates so. Overtons has them on sale for 59.99 - $5 if you use a code I found. $ 60 after shipping so for a cheap depth finder in the...

    81 mercruiser 120 cavitation or out of gear?

    Out on lake today. Boat ran good. Would pull tube and plane with no problem. I noticed if I pulled back on throttle below 4k rpm after getting on plane, that if I rapidly move throttle to WO it acted just like it was slipping. I thought at first that the coupler broke. But yet out of the hole...

    82 Galaxy 180 merc 120

    Are there any downloadable manuals for the motor? I have the one for the drive. I just bought this boat and started fixing it up. Transom seems sound but how does one really tell it is rotted? Currently the boat has a 19P prop on it and getting on plane with 2 people is quick. The tach goes to...

    Prop spacer for '72 50hp johnson do I need it?

    I bought a PJ-81 prop for my '72 or there abouts Johnson 50hp. The 14x13 oem has a thrustwasher on the inside that fits into the prop bore. It does not fit inside on the PJ-81, it would if the rubber was moved in further. Do I still use it or what? The shaft does have a taper so something is...

    %0hp Johnson prop question

    I have a Bayliner capri 14.5 with a johson 50hp 1972 large gearbox. The old force 50 junk would do about 32 mph on the speedo (inaccurate I'm thinking). The johnson has a 14x13 on it and I put an omc tach on it set to 6- check it with hand tach and really close. I can nail it and it jumps onto...

    late 50's early 60' evinrude 40

    I have an evinrude lark 40hp electric shift. Runs good but the problem is it has a 23" shaft. What would that have been for. The old boat I had it on had the back braced up with aluminum plate and a 2x4 between to raise it. Can this be easily and cheaply converted back to short shaft? Or if I...
