    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...

    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.

    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.

    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...

    20 foot 1997 Maxum 2050 bowrider propeller question

    Thanks a bunch for being involved, other end of the world but great nonetheless. My pro is a 4 blade aluminum. The thing about this boat is I rarely took it out in the past 10 years. I recentul rebuild the drive, all the rubbers, some bearings, used the proper dual torque yes. I usually do my...

    20 foot 1997 Maxum 2050 bowrider propeller question

    I took care of that, it was adjusted too close and was killing the throttle so I twisted it out and now it's ok. The rpm varies but it's at 650. The timing in the video varies with the rpm need to find out at what rpm it needs to be to have timing at 10btdc.

    20 foot 1997 Maxum 2050 bowrider propeller question

    I want to show the timing check again. The mark drifts left and right when idle goes from 630 to 1000 and back. But it doesn't seem to be at 10BTDC, more like 15 to 16 BTDC. https://www.dropbox.com/sh/xonptswxmb9y5ef/AAAbLVPhak6XmB1On9isXk8Ba?dl=0

    20 foot 1997 Maxum 2050 bowrider propeller question

    Just thought of something, the accelerator cable that goes on the carb, I have long suspected that it needs some adjustment since when using the remote control to accelerate it doesn't respond right away. I wonder if that limits the amount of throttle that can be achieved?

    20 foot 1997 Maxum 2050 bowrider propeller question

    I don't know the manufacturer but it's a 4 blade aluminum. I don't know if 14.5x17 or going down on diameter to 14x17. How much of a difference does 1/2 inch diameter down make? Also1 inch pitch lower.

    20 foot 1997 Maxum 2050 bowrider propeller question

    Been reading, did the turning point wizard and I came down to 14x19, 14.5x17 or 14x17. Any thoughts?
