And I wasn't offended in the least by it. Like I said before this is the first time I have had a motor built other than diesel motors. This started out looking for 500 HP period. After the way Ron built them for the torque I now see that just the change of the fuel systems could make these motors a lot more than they really are. Will I make that change right now? NO I will not I want me boat back in the water so bad I can taste it now. I pushing the 8th month now and still I haven't even heard them run yet. I honestly have spend enough money for a set of whipple motors and here we set talking about these old fuel systems making a huge difference in what I have paid for. Am I happy about all of this of coarse not. I just want it over. I go threw the classifieds all the time and I see motors with a whole bunch more power then mine for half the money. I wish I had just went with new crate motors from Mercury. I might have but the sales rep was too busy trying to sell me a set of 383s.In stead of what I wanted. I thought this guy is out of his freaking mind. The rest is history.

Doesn't take a lot to spend a barrel in this game. Just wish I knew a little more about what I wanted. But next time I will know exactly what I want being that I have done this once. I haven't had a lesson yet that I didn't pay good hard earned money on. But I'm sure I'll have my moneys worth this time too. I have nothing left used except the fuel systems we have been jabbering about for a few days now and it sounds like that will be a easy fix too. Ron says power wise I'm just inside of what my bravo's will stand if I don't go jamming on them and treat them like a lady. LOL

On a positive note and moving right along. I was at Potter's shop today and my manifold are on and measurements have been taken for the tail pipes so now we wait for those to come in. Looks like they were putting in my new gauges this afternoon. Ron stopped by my shop to measure my hatch cover for clearance of the risers. Here is a question for the rest of you Fever guys. My exhaust holes were cut right up under my swim platform. In other words the platform from under the bottom cuts up for about a foot then drops down and flattens out. The exhaust holes were cut in that dip of the platform and the exhaust was actually burning my platform from the dip on out. Any one else confirm there's is like this two?? This is a little bit of a problem for the new tails. Ron is says he is trying to get the tails to be angled down wards from the risers out. this way the exhaust will blow down past the dip in the platform. Its a good thing I don't want mufflers on mine cause they wouldn't fit because of the dip. Ron thinks the holes were cut to high in the transom. Guys jump in and let me know how yours are in this area please!!!!!!!!!! I wish I had the plugs for these holes. I would plug them re glass and recut them lower by about three inches. Maybe this had to be this way for the stock Mercury manifolds. Let me know your thought's please.

Let me look at my DYNO sheet 1st so I'm correct about what I'm about to say. This thread as taken so long I don't even remember the beginning of it now. LOL. Yes 532.9 HP with bad fuel regulator. 619.9 FT LBS of torque. The other is 529.9 HP I believe also with a bad fuel regulator.

Oh, I get why everyone is confused.
Page 1 and 2, you said 502MPI's where coming out and he was building you a set of 500EFI's.
Me comprendo.
What you should have said was he was going to build you 500HP engines using the MPI intake and fuel injection system.
Again, big HP differences/limitations between the 415MPI/500EFI/ and just to throw it in their, 525EFI intake set-ups.
All figured out now.
I did not read whole thread, but if for some reason the thread is this long cause you don't know why it didn't make more power it's because you had him build you 500HP motors and thus why the MPI intakes where kept.
If you understood what hp he was building you, as it seems you did by saying he was building you 500hp EFI engines, then all is well and enjoy your new motors.

I think you will be happy when you get your boat back. you have upped each motor by 120 hp. I do agree your current intake and injectors are at their max, but to go to the next step is big bucks! Ron has built you some great motors out of what you had don't get caught up in the hp wars. Go enjoy your boat it sounds like a great one.

Yep, sounds like they made really good torque. You will feel that. It's summertime......enjoy. Those last few mph in a Fountain come slowly anyway. It starts to get lonely much above the mid 80's. Don't get me wrong, I am glad I have been there and want to do it again but for now I am good with regular oil change intervals, running 80 and burning 87.
I have friends that tune and props test all summer. They can squeeze out a few more mph than me but we mostly ride together?

hey we know a guy that had a potter 625 that made his 22 run 85mph..was not fast enough so he took his engine out and paid him for one of those 700's and paid a member on here to put it back in,,here is the kicker..8k plus later the boat still goes 85 mph..i remember one of our friends has the exact same boat with a 525 efi that goes 84,,,so what gives lol..
