    1990 Force 120HP #2 Cyl zero compression and upon opening piston shows damage

    I agree this boat is new to me and I did not check it properly when I got it, my bad, but I am in the habit of fixing everything I get. I already changed the dash gauges and actually resurfaced the whole area. he fishing season started. I was doing other things like a trailblazer rebuild, 12 BMW...

    1990 Force 120HP #2 Cyl zero compression and upon opening piston shows damage

    Thanks. Once I measure the #2 cylinder after cleaning it I can see if it needs to be bored. I can probably hone it. Any idea what size pistons these have I see .010 all the way to .040 but what is stock? This piston just started to get damaged.

    1990 Force 120HP #2 Cyl zero compression and upon opening piston shows damage

    So I was on another thread and was asking about timing one person told me I might have engine issue to which I said no way. Well it turns out he was right this is a dual 120HP 2302 Trophy. Haven't taken it out since last year and I had the 2500 RMP discovered the plate was not adjusted right and...

    1990 Trophy with twin Force 120HPs need help on timing and idle adjust

    You were right cyl number 2 read 0 or 5 compression on one engine and 110 on the other. Is this a headgasket issue or piston rings and/or cylinder. All the rest read between 125(1 and 4) and 128(for the number 3). The plate on the lower carb was causing the 2500 RPM but cyl is bad. I have to get...

    1990 Trophy with twin Force 120HPs need help on timing and idle adjust

    OK I just got a picture sent from one guy with one of the manuals and the 120HP that has the Prestolite ignition needs to adjust to 28BTDC. The thunderbolts are at 32BTDC. That is great to know. I initially put it at 32 but did not run or turn it on. I will go change and do the compression.

    1990 Trophy with twin Force 120HPs need help on timing and idle adjust

    Issue with the motor? Nah It's a dual engine and one engine was running at 2500 RPM. Not knowing where the idle adjustment bolt was like a moron I messed with the timing bolt. So I have to do timing. It turned out to be the lower carb plate was not in sync with the top one and I had to loosen...

    1990 Trophy with twin Force 120HPs need help on timing and idle adjust

    I bought a book but it's a 92 model with the thunderbolt ignition mine is Prestolite. On the timing the thunderbolt shows cranking at 32 to get 30 degrees at running. I have no clue if mine is the same. I see 28 degrees all over the place so I am here to make sure. Also on adjusting idle on the...

    Need advise on older Trophy boat stress cracks fixes and more

    So you're talking about the stringers by the transom area right? The transom has been emptied and converted to composite as I mentioned. I got myself one of the Tramex MEP Moisture Encounter Plus Moisture Meter.

    Need advise on older Trophy boat stress cracks fixes and more

    Thanks for responding. Can you be more specific on that? You're talking about drilling behind the cracks at the stringers by the transom? I can get to the stringers through the battery compartment on both sides. Trying to learn on how to do that. Not versed on it all yet but getting there.

    Need advise on older Trophy boat stress cracks fixes and more

    So this boat is in really great shape in and out. Still has the dual Force 120s oldies running great but the deck has multiple stress cracks all around the edges. I want to fix that, I do believe the color is white don't know if it's a particular shade of it. So I already have some Total Boat...

    20 foot 1997 Maxum 2050 bowrider propeller question

    What would be an acceptable slip number. With the 18 pitch I got 14. If the numbers stay with a 17 I get 9. That would be pretty great

    20 foot 1997 Maxum 2050 bowrider propeller question

    Your understanding of this issue is basically like mine was at first. But in boats it seems you first make sure all is adjusted with the engine, RPM, timing, carbs if you have them, compression and then you make sure the prop gets you at proper RPM at WOT. And let me tell you if you're not you...

    20 foot 1997 Maxum 2050 bowrider propeller question

    I read you I ordered a 14.5x17 to at least get me in the ball park rpm at WOT. I don't remember what the original prop was but I have a feeling I went up an inch when I replaced following the same theory that bigger is better. I am not 100% certain of this but I get that feeling.

    20 foot 1997 Maxum 2050 bowrider propeller question

    I see what you're trying to say it's 24 for the advance only plus base in my case 10 for a total of 34. At least that's what I read.

    20 foot 1997 Maxum 2050 bowrider propeller question

    I have one already it's in the videos I posted. But I thought that 32 is max. That's what people have been saying on different threads.

    20 foot 1997 Maxum 2050 bowrider propeller question

    Was just reading on the vacuum advanced on my thunderbolt V since it's 10 at base idle 650 rom what is the total timing advance at, 32? And at what rpm, 3500? Wanted to check that too as the guy at the boat place said I should. This doesn't have to be done in Base mode right? And in the water or...

    20 foot 1997 Maxum 2050 bowrider propeller question

    I did the Base timing check and in my opinion it's right on 10, manual says 8 though but close enough see for yourself. Also there is a picture included with the purple white wire. I will redo the mixture at 1 1/4 and set idle at 650. The speed has to be done in the water I think...
