    Sherwood crank mounted pumps compared to Johnson

    Now that I'm well into my second season with the 8.1's, I really do like the crank mounted RWP setup from a service standpoint. Which with these pumps, is all the time :) I have the P110's which don't have a great reputation but are an easy rebuild and/or swap. On the issue I just had (failed...

    8.1 overheated and aborted trip (for now)

    8.1 overheated - aborted trip. I broke down for the first time ever yesterday and came back to port on one engine because my Stb engine overheated. I was about 25 miles into a 70 mile trip and cruising along nicely. All of a sudden, the RPM’s dropped and my exhaust hose temp and engine alarms...

    rebuilt 8.1's - break in period/oil consumption

    I still have a couple of minor nagging issues which I have in separate threads below, I will come back and close those out. All told, I've put 41 hours on the rebuilt 8.1's and wondering if I should be concerned about the oil consumption. I might have mentioned this in a prior post, I have a...

    Crusader 8.1 - Racor gauge readings

    I installed new Racor gauges in an effort to narrow down my surging issue on my Stb engine. I had generic gauges installed a few years ago but they didn’t last and I like the way these new ones “hold” the high reading. As usual, the results are not clear. To recap, my Stb engine has a surge...

    8.1 - bunch of codes

    I’m working my way through a punch list of items while I break in these new engines. On my Stb engine, I noticed a low RPM (1,500 or so) surging of a few hundred RPM’s. If I throttled past that, it was fine and I cruised at 3,500 for a few short periods. When I tried to briefly push past 3,600...

    Crusader 8.1 - no start or click

    I’m getting really close to splashing my boat with my new/rebuilt 8.1’s. Out of the blue, my port engine will not start. Ignition switch forward, gauges light up but not even a click. I’ve gone through these top/bottom and started each one at least 15 times now. Starting to backtrack what I’ve...

    Crusader 8.1 - install issues/punch list

    I have both engines installed now and have run both. I wanted to do a few test runs before winterizing but a couple of cold forecasted nights "forced" me to winterize yesterday. I probably jumped the gun and they would have been ok. Anyway, I have a few start up issues which I really didn't want...

    winterize w/o starting - raw water side?

    So it looks like my engine buyer has flaked so I have the 454's listed if anyone is looking for a pair with straight drive transmissions. If for some reason they don't sell until the spring, is there a way I winterize the raw water side without running them again? They're removed and inside...

    Fuel line I.D - 454/8.1

    The fuel lines on my 454's are 3/8" I.D. which it had from the factory. I replaced all of them with the exact same aeroquip hose when I bought the boat and that worked fine. The 8.1 install manual specifies 1/2" I.D. which raises a few points: 1) The fuel pump cooler/inlet is 3/8" so that...

    Finally - pulling the old 454's out on Friday

    It's only been a year since I bought the 8.1's and it looks like they'll finally going in! Step one is to remove the 454's which is happening on Friday. I built cradles for the 8.1's which are in use. I'm going to drop them both behind my boat while I figure out when the buyer is coming to...

    Crank mounted raw water pump wobble

    I got my second 8.1 back from the machine shop and was hoping to do break in run today but my (new) fuel pump is dead. I’ll swap over my other and run it hopefully tomorrow. One item on my punch list was one of the crank mounted pumps which has a wobble. They’re Sherwood P110’s. Since i was...

    8.1 re-power update and question on camshaft timing before start

    I can't believe I've been doing this for almost four months, I could have built another house by now :) I got engine #1 back from the machine shop and doing the reassembly now. This is the one that had the horrible oil analysis and I have to say they pretty much nailed it. I wound up going .30...

    8.1 water in exhaust manifold and update

    I’ve been working on the 8.1’s I picked up about a month ago. In the process, I have been delaying the inevitable, the cylinder walls need a clean up so I’m going to do a more invasive teardown. It’s cold out and they’re sitting in my garage so I would be stupid not to invest the time now. That...

    ugh, got my Blackstone reports back on new engines.

    I knew going into this I would need to catch up on deferred maintenance. I pulled oil samples from each engine and sent them out to Blackstone and just got the results back today. The Starboard side report isn't great but I think it should be ok and I have fixed any of the offending bolt on...

    8.1 fuse block

    One the many things I’m doing on the 8.1’s I bought are the outstanding recalls. There was one involving the fuse block, cut one wire and cap and then splice with another. Both engines had this done but one had a horrible, non shrink crimp thrown on. I’m going to re-do both but as you can see in...

    8.1 - finding TDC

    How do I do that w/o any timing marks? I tried using the screwdriver method but it gets jammed, I think because the pistons don’t have a flat top. I did this on my 454’s and it definitely does not feel the same. Do the 3 holes in harmonic balancer mean anything? I also don’t see a rear timing...

    Crusader 8.1 wiring - bench test hookup

    I got my 8.1's home over the weekend and have them in the garage now. I want to do sometesting and run them a bunch of times before I start thinking about the swap at the boat. I can't find a wiring diagram that exactly matches the color coding I see on my harness. I have it hooked up now to a...

    picking up 8.1's - pallet or cradle idea

    I'm going to be picking up a pair of 8.1's next week. My plan was to put each on a pallet (tied with ratchet straps) and have them dropped into a rented pick-up. A standard pallet is 48"x40" so I should be able to fit both if they go in sideways. The bed 48" x 94" (just a shade under 8') I did...

    8.1’s - known weak points, what’ll leave me stranded?

    While I have a little time, I’m starting to put together a list of things I want to do on the 8.1’s I’ll be picking up in a couple of weeks. When I bought my boat ten years ago, I replaced virtually every bolt on part on my 454’s since everything was original. The only original part left on both...
