July 15th Update

Sorry, its been a crazy few months but here is an update. I've made some good progress and she is almost ready to go back in the water. Sorry about the crappy pics, most are from my iphone.

Prepping the port engine for install

New billet cam position sensors. A nice upgrade over the cheap platic ones used by Merc (one of mine was cracked)

Updated tail end. I installed the new style ECU mount, new coils (had to extend the coil trigger wires). You can also see the new coolant resivoir.

Port engine installed!

New style power steering resivoir, which required new oil filter base, which required new oil hoses, you can see how this project has grown.

Port drive in place (XR/Imco) with new mercathode, new trim hoses and trim rams plus upgraded poly bushings.

Both engines back in the boat!

Close up of the new poly trim ram bushings

what advantages do the poly bushings offer?

Same as in a car, less wear and firmer material mean less movement. Probably overkill unless you are running 100+ mph but I had to replace the old rubber ones anyway and they were not much more money.

Ok, they are in and running! The cam definitely added some additional volume to the sound levels. I think you can hear it in the next state, lol. I picked up about 5mph with the upgrades. Unfortunely, I still have the uneven power issue. Not many things left to check. Next weekend I am going to swap the ECU's. Once I get that figured out and fixed I will start tweaking the prop and hoping to crack 80!

Cool thread! Any updates?

check the props, and swap the drives around, gimbal bearing getting bad, a lot of outdrive issues will cause these power issues, also make sure the tach is accurate. but on another note, those look great,

great job !!! good luck on the rest of the tuning !
