Alright guys......
First off thanks a bunch for your help on the engine mount bolt torques. I got a lot done this past weekend. Both the Grady-Drive bracket and the engine when on without any problems

.
Got the Grady-Drive bracket on boat this past Friday and sealed with 5200. Sealed the bracket onto the transom and sealed the bolts both inside and outside of the transom. Let the bracket set over night so the 5200 had plenty of time to set up. Ran the waterhose over it Sunday and so far no leaks

.
Sat evening mounted the engine. All I have to say is that it sure is nice having a tractor with a front bucket. Made the job MUCH easier. Bob, I took your advice and torqued the engine bolts with the box-end wrench and pulled them up until they were "tight-nuff" then put the jam-nuts on and got them "got-en tight). Sunday I hooked my jumper pack up to the engine and worked the tilt/trim to tilt the engine so I could move the boat out of the shop.
Now...here is my current problem and in one word...rigging.
I see how to hook-up the throttle, shift cables, power from the battery, fuel, and oil. I don't think I'll run into any problems there. However, there is a 10-pin cannon plug along with 2 other plugs at the front of the engine :? . My old engine ('91 175 yama) did not have these connections. The connections were made directly to the sensors and what not. I talked to a guy yesterday and he said that I may have to get a new tack, speed-o and a "Boat Wiring Harness" to get everything to work. I'm hoping I don't have to change the instruments out since they are working great. So here is my questions:
1. What is the 10-pin cannon plug and the other connectors for?
2. Are there any adaptors I can buy to get my old instruments to work with the newer engine (fyi; going from '91 carbed Yama to a '99 OX-66 fuel injection)?
3. What systems will I need to monitor on the newer engine that I didn't have on the older engine (Fuel pressure, coolent temp)?
Thanks guys for the info and yes the project is looking good 8) . Pics will be coming soon.
