    Downsizing Hydrofoil Fin?

    I've got a 17' Aquasport with a 93' 115 Merc. The motor has a hyrofoil fin bolted to it. I like the way the fin pulls the bow down into the water but I feel it pulls it down too far, especially at high speeds. Has anyone ever tried cutting a small portion off each side of a fin to lessen it's...

    Control cable loop... how big??

    I have a 93' 115 Merc 4 cyl. on a 17' Aquasport. As you can see from this pic I need to replace my control cables.

    1993 115hp 4cyl<br />I replaced my water pump yesterday, my first time on an outboard, and think I may have screwed it up. When I fired the motor up today at the ramp water was leaking out where the shift shaft goes into the lower unit. Here's a pic that shows this.<br /><br /> <br /><br />I...

    93 115 Oil Injection?

    I have a 1993 115hp 4 cyl. I was doing a little reading on old posts and found some discussions about Merc oil injection systems. I sounded to me that a few of you don't hold much faith in the reliability of the system on the older engines. My question is if you owned my 1993 motor would you do...

    Mercury Ignition Key

    Hi all, I figured this would be a good place to ask this question since this board helped me with my motor a few months ago.<br /><br />A friend of mine had her purse stolen yesterday. One of the items in her purse was her boat keys and she doesn't have a spare set. How can she go about getting...

    1993 115hp Help

    I recently purchased a used boat that has a 1993 Merc 115 4cyl motor on it. The serial # is OD190240. The motor seems to have been maintained well, it's very clean and everything appears to have a good amount of lube. I'm planning to replace the water pump and thermostat just for peace of mind...
