So it’s kind of bad news, good news, bad news.

bad news #1. Can’t find a Holley terminatorX 550-905 or 905t anywhere. If anyone can make a suggestion on where to find one or a different tunable system that has a harness, O2 sensors, and supports MPFI. Otherwise, I’ll be waiting until mid-late August (hopefully).

good news, as I was thinking through how the elbows and risers work along with closed cooling it occurred to me that water might be flowing over O2 sensors. That would be catastrophic. I didn’t want to change these out regularly. I see no worries fir that.



you can see the O2 bungs here.

i do have the parts to install a crank mounted raw water pump. It’s kind of cool when you think up an idea to have a machine shop build and then a little discouraging to find it’s already made. But I suppose that is reinforcement you are on the right track. I’ll post those pics and parts when the whole system is here.

Bad news #2- this is kind of painful

the bravo 3 outdrive I purchased needs a full rebuild. Gear set, cone clutch, shims, seals, bearings, everything- but case, props and shafts are done.
I’ve really considered going alpha route but I’m too far in to turn back now and Bravo is clearly better suited for my application.

I was told it’s pushimg $7k for that job before I buy the gimbal housing another 3k. I got the parts list and found a way to trim some costs down. I expect it will be 4.5k-6k. And then the gimbal housing at 3k. A new alpha is under 3k for whole thing and while that appeals to my wallet. I don’t think that is a wise long term choice. But oh this one hurts, ouch really bad…

we decided to go with 1.81 gear ratio. Originally it was a 2.0 gear ratio. We considered a 1.65 but we’re concerned somethings gonna give as that was not designed for these shafts as well as the load on the engine. Given it’s primary role of fishing we decided to play it safe. I have the parts lists if anybody wants them. Partsvu.com says it’s $3k out the door.
