Bought a kicker... need a lower unit tho
 

sooo I went to look at a "'86 merc 7.5" today and bought it... I believe it's a 1975 model tho... The lower unit is munched but the engine runs great.
I gave $100 for it so I think I did pretty well.
Now on to the details.... My engine serial number is:
4132901

If I run the number it comes in as a 1975 merc 7.5 hp model 75......

How do I determine whether a certain lower will fit or not?
Looks like the part number on my lower is IIRC 1630 3916 and I found a 1630 4407 for $50

wish i knew you needed one, I have a couple real nice evenrude 9.9s id sell cheap. Not sure how much they would cost to ship though ??

shoot, I'm prolly goin right past you on the way to mass but my idea of real cheap is bout what I gave for this one

Post a pic of the engine. The shape of the cowling and the color of the letters on it will tell what year engine it is.

Acording to Master tech Marine web site serial # 4085865thru4314384are of 1975 vintage.

yep same thing I came up with... I don't have a pic of it yet but eventually....

About my idea of cheap also...LOL

But Kevin, that's more than you paid for the entire V, isn't it?

like $100 more LOL

I have a nice sailboat prop 5 Pitch elephant ear prop for that motor if you get it going. Check the wires on the switch box and make sure they are not falling apart before you invest in a lower unit. The switch box costs double what you paid for that engine.
