I forgot to say it above, despite my long monologue into the wind, but I think there is way too MUCH transom lift. And I think the nose cone is inducing it also. I could be wrong, but this boat is so freaking light it's hilarious. I can lift the front of the trailer 4 feet in the air and move...

I literally lost some sleep over this, so I'm going to brain dump to try and feel better. I think it's the stupid nose cone. Here's why. First speed run ever on the first test run ever was trimmed up halfway and we did 38 mph. Then my cousin wanted to look at the motor so he moved to the back...

I had this conversation with our real estate agent friends. They say in order to make that whole situation work you need two houses. It's not worth it to rent while you wait for the market to crash, so you gotta live in your "other" house after you sell your big dollar one at the "top". I mean...

I feel like in the midst of all my rambling nonsense we need a recap of what has happened so far. At 7" from prop to pad I did 43 mph and could not trim up even a millimeter from full down position. At 8" from prop to pad I did 52 mph and could trim up for miles until the boat got super duper...

Well isn't that interesting. Hmm. And that's exactly why I came here. Listen I'm not trying to ignore everyone and say everyone is wrong. I raised the motor another 1/4" but I have to wait another 2 weeks to test. I would love to test it every day, and update the thread more often, but I can't...

Dang, that's vintage for sure. What year is that?

I realize that. Also, I picked up 10 mph dropping the motor an inch. So I am torn. Do I follow thousands of Google results for putting this motor 6" up from where it currently sits or scoot it 1/4" at a time until it blows the prop out again? Maybe there is one other guy out there with a 1976...

I think you may have missed the OP and history of this thread, lol. 1" up from there was prop blowout city and absolutely zero up-trim ability. And that was at 7" below the pad. At this point in time I would have to raise the motor 6.75" to bring it to where you are saying, lol. Although I'm...

Alright, will do. I was doing so much testing and tuning I left it off for both trips. I figured given the horrible state of everything else it wouldn't make *that* big of a difference. Like for example, I still need it off because the carbs aren't synced. Top butterfly lags behind the bottom...

Alright here is another photo of where the motor was for 52 mph @ ~4200 RPM. Keep in mind this motor is probably only making 120 HP, lol. I can't even trust the tachometer either, TBH. I raised it 1/4" from there. Next test is around Easter weekend. Just as a sanity check, currently the...

Water pressure gauge works and had plenty of water pressure. I'll try going up 1/4" and see what happens. Side note: when trimmed up "all the way" (or what I felt like was all the way, what it could take) when I let off the gas the whole boat dropped down into the water with a big shift in...

I am a total newbie and will take any theory at this point. That sounds like a valid one. It's possible I had a cavitation bubble on the prop from the broken trim tab on the cracked skeg...but with so much more MPH and up-trim available do I dare raise the motor now? Only 1/4" maybe?

One more extra reply. There is a slight chance I got into the resonance zone on my super duper sloppy steering and steering to mid section slop. If you wiggle the motor in free air the thing wiggle wopples all over the place. Like damn, are there any rubber bushing in there at all? It's possible...

Video of the day

Well, the biggest change was dropping the motor down 1" and I picked up almost 10 mph! I had loads and loads and loads of up-trim available all of a sudden now, no prop blow out except for one little weird moment at full up-trim, and zero slip at all during hole shots. So the hub on the prop...

Haha! I've only done it in our 21' Shockwave jet and I don't think I'll do it with my outboard Tahiti... yet, for several reasons. Shockwave is getting the motor rebuilt and the Tahiti has 15 minutes of testing time on it and is literally sinking (I'm patching holes right now). Like others have...

You're telling me! I wish I would have known this before attempting my first ever fiberglass job with 1708, lol! Tried to glass in seat mounts that look like stringers. Ughhhhhh..... Next time I'm trying 1208 or just 1200. 1708 doesn't want to go around corners at all and is so thick it's air...

No. People don't usually leave anything tied to the docks unless it's a PWC up on one of those plastic ramps that gets the whole thing out of the water. The water units released from Davis are completely dependent on what the farmers want and can range ~6' in a couple hours or more. In winter...

Well that would suck. So the other day I was able to spin the motor over by hand while it was in gear using the prop. I was fighting against the compression of the motor somewhat hard and it didn't slip. Would that be a good test or not?

I'm gonna say no.
