Mercury Connection Compadibility

[Kidgold]

I have a late 70's 115 Mercury Outboard (6 cyl). The motor runs great but the boat it is on is in sad shape. So, I wanted to upgrade. I found a really nice 2000 Sea Ray 18ft without a motor that I am thinking buying and transferring the motor. But, I am not sure if the wiring plug, steering, and fuel connections will be the same? Does anyone know? If it won't directly connect, how hard would the modifications be?

Re: Mercury Connection Compadibility

Steering should be standard. We need to know what kind of engine was originally on the 2000. If it was a Merc I'd assume the fuel connection would be the same and if not that would be a super easy fix. As far as the controls though....you may have to reuse yours but hopefully someone will come along with better knowledge than me on vintage/newer merc controls.

use your the existing wireing harness, mercury changed harnesses quit a bit. the plug at the motor is the critical thing. controls are not interchangeable between brands.

As far as I can tell from the Sea Ray website, the 2000 OB model came with mecury OB, actually the exact same size motor (115). So, the controls should be mercury, just a lot newer. It sounds like the steering & shift rods should bolt to the older motor. But, I will probably have to cut & splice the electrical connetion to my existing plug into the older motor. Do anyone know where i can download a wiring diagram for both years of the mercury motors (78 &2000)?
