Mercruiser 888/302 Shift Plate Update Install

[Skymac]

Hello,

I have a Merc 888/Ford 302 setup in my houseboat. In the process of cleaning up wiring and getting to boat to 100% I have decided to upgrade to the new style shift kill switch and plate as referred to by Service Bulletin 02-01. Reason being that most of the time, coming out of gear the engine likes to die when the old roller switch activates, even with adjustments, just very sticking and gummy. I also do not have trim on this boat anymore and therefor I won't have to mess with a new trim reverse switch. The shift cable and outdrive are in great shape, actually did a bellows install yesterday and got the boat back in the water. I have the part number 864363A1 but I'm not for sure if this is what I need or not, it came with some two sheet Mercury instruction pamphlet that is totally useless. Has anyone ever done this mod and have pictures or can provide advice.

Thanks for the help,
Justin

Should have replaced the shift cable first, corrosion and the cable are the 2 culprits.
Install the plate in it location, connect 1 wire to the white or white/green wire coming from the ignition, connect the other wire to a good ground.
Can I have the old parts?

I had a brand new shift cable in the package but inspected the one I had in the boat and it was in excellent condition and moves good. Just took the new one back to the shop. That's my problem though, I can't figure out how this new one mounts exactly. If I could find a picture I'd probably be set. Once I get the new version installed and running you can most certainly get them. I actually have 2 old plates and mechanisms off 888's.

http://www.boatfix.com/merc/Servmanl/6/6C1R3.PDF page 1C-38 You should have a new pplate and switch assembly ,so its mounted on the stbd riser and thats where the cables connect. Thinking your cables are more of a push-pull setup with a reverse lockout.
This is the new plate, correct? http://www.ebay.com/itm/Mercruiser-Shift-Interruptor-Switch-864363A1-39670A28-/360819161999

If you still have the log style and not the center rise style then you will need to make a mount to bolt the new plate to first
then install the cables in the new style positions

Yup that picture is what I have and the eBay part is the new part I have. I'll look at it this coming weekend, but I'm still digging to see how it mounts exactly.. I'm just brain dead right now, did a full motor swap on the houseboat yesterday and have everything done but I had to order some new gaskets/restrictors for the risers, besides that it's all done and running.

and what I mean by how it mounts is how the cable attach to it and properly pivot. I see what you're talking about on the physical mounting of the bracket.
