2 wheels done . . . 4 more to go. I am also checking the bearings and adjusting as needed. They look OK . . . So far, one wheel was a little tight and the other was a little loose.

We are going to be traveling quite a bit (more than a wee bit) this Fall, so the boat will probably come out in Late-September - Early-October. . . who knows. That is why I have been trying to squeeze this work on the trailer in. The fact that the calipers were not seized, makes things a whole...

The paint and the brake pads arrived . . . Just waiting on a few more things. . . I got the rust reformer on the remaining 4 calipers and will give them a top-coat (silver) in the AM. but . . . The Admiral wants to go out on the boat, so who am I to argue . . . :ROFLMAO:

I tend to mix the NA beer with some high-octane beers, such as . . .

I have Celiac Disease, so it is gluten-free beer for me. Go Brewing has a few gluten-free, N/A beers that I keep in stock. 45 calories. .

I've got my repair process line going . . . Remove/inspect/Clean-up (left) Rust Reformer (right) Silver topcoat (center) . Here are the disc rotors . . . . 6 on 5.5" The angle grinder is not putting enough friction/torque on the rotor to spin the wheel with any certainty. I've got some...

Also the throttle body is a single field replace-able unit (pricey), but it has an internal actuator (motor) that actually opens the throttle per the Arb. TPS value. I am wondering if the full movement of the throttle plate can be / has been verified (ignition on, engine not running, throttle...

I have a bunch of runs on my 6.2L which is the bigger brother of the 4.5L, so I can cross-check some of the data from a behavioral aspect.

The range for WOT RPM is 4800-5200, so 5,000 is a good target. Are we at altitude? MIL sitting in the back? :ROFLMAO:

A couple things I noticed so far . . . Not saying those are the issues, but . . . TPS at idle is 4% . . . Seems high, but maybe it is normal for the 4.5L Engine is reaching 4500 RPM as per the later run on August 4th. Still wanting to see a run in throttle increments to see where things...

Just trying to catch up on this thread . . . sorry but I have not read through every post . . . Back story is . . . New to the OP boat/engine, prior performance numbers unknown (?) 2016 Engine, has some sort of warranty history and then offered out in 2018. Engine won't go over 4,350 RPM...

@damo79 . . . I took a quick look at the files, and will look more in the AM. One question . . . the files tend to show the TPS1/2 and arbitrated TPS maxing out briefly, but then come down. Are you reducing the throttle or is the engine deciding to do that itself? If you can / need to, make...

I am traveling home today and should be able to give those Diacom file a look later in the day.

. . :D

I still have the Diacom software, PM me if you want and I'll send you my email so you can send me a file or 2 for an additional set of eyes on your data.

Yes, I was thinking the same . . . got to get some more 40 grit discs though . . . I only got 60 grit and higher in my supplies. :unsure:

Now that my boat is pretty well squared away, I turned my focus to the trailer. It has disc brakes on all 6 wheels, but they have not really worked in a long time. I figured the calipers may be seized, but they are actually OK . . . they retract easily. It looks to be that the pads were so...

Now that I am an outboard guy, my knowledge on the Mercruiser front is quickly fading :oops:. . . but just taking a look at the data, a thought that came to mind was the throttle plate. (loose, linkage, something.) :unsure:
