Thanks Kevin and if I seem a little prying with detailed questions well it is because I have discussed this set up with Tyler also and have been waiting to see how turn key this is. I will tell you I am real happy that you can FEEL the difference in performance.
Feel free to ask me any questions that you have, I will answer anything as honestly as I can. I will see how this season goes, but if the first trip out is any indication, I will be very happy!
I also need to move the fuel pressure guage so I can get a more accurate reading. For those that have them, where are yours located? Also, I am looking for one that might just connect to the shrader valve at the front of the fuel rail....anyone know of such an item?
Here is a link for the Fuel Pressure gauge you are looking for...

That looks like it might work. Thanks.

Thank you.
Just a little update.....
Had the boat out this weekend on Lake Mohave. Did some fuel pressure adjusting and some high speed runs and was able to push the 26p to 5400 rpms with a full tank of fuel! Best I saw on gps was 73.5 with 3/4 tank of fuel. I am sure that with a light load of fuel and a little more work on the trim that I could see 75-76!
That about does it.....now I should be able to just use it.

And how is that compared to previous numbers? I can't remember what you were seeing before and with what prop.
Best I ever saw on gps was 71.2 mph going down river in front of Park Moabi with no fuel and 2 peeps at 5400 rpms with a 24p. On the lake best I saw was 69.9 mph with full tank and 2 peeps with the same 24p prop. Now I can push a 26p to 5400 rpms with a full tank and 2 peeps. The best part of this rebuild has to be the mid-range! From 3000 to 5000 rpm I can put your back against the seat and keep it there. It is absolute amazing compared to the old motor. I am very pleased with the results. Now I just have to remember to be easy on the sticks so I don't blow-up my drive!
Hey Boyz,
Looks like you all know alot about building 502 motors. Just picked up 94' warlock cat 25sxt. Did a little home work and found out is was a 502 gen 5 HO, I think? Looks like they started rebuilding the motor. when I pulled the valve covers, Looks like those pretty picks of those rolling rockers i seen in the thread.
Need some pointers from all.
The boat motor wasnt completed and has no carb or distrubtor? Any pointers on the best carbs for that type motor with black hawk merc dual prop. I was thinking holley, but I really dont know?
PS There is a whole in the hatch cover?
Want to insure that I do it right, where the last master left off.
Also, is there any schematics on connecting wires lines etc? I need to double check everything. I'm a wannabe mechanic and dont want to screw up anything. Any pointers send them on.
Thanks
Jeremy
Jeremy - You might try asking these questions in the Gear Head section, too. The one I built here is an EFI engine, so I am not in the know with all the carb questions. The hole in the hatch is probably from previous setup with a blower. As far as wiring diagrams and such, get a copy of the Mercruiser manual. It will have all that stuff in there. Good luck.
