I bought the boat in Oct 03. Always ran 4800RPM and the gear ratio is 1:50. Thanks again for all the help everyone!

If you know

1) the engine is in a perfect state of tune and making the correct power - compression ratio is ok ie motor not tired etc

2) You know the RPM range of the engine is higher than 4800 rpm

3) There is nothing on the hull, outdrive etc causing drag

I would send your prop out with all the info you know and let them spec it and tweak it.

right or wrong i dont know i was told stock distators can retard and or the revlimter hold you back, i repaced mine with msd 6200 chip and had miles of smiles

Bob T and anyone else with a single 29 and planing problems - one thing that helped my 29 (single 525SC with aweful planing times) was the addition of larger tabs - replaced the small k-planes with the next size up (380's?) - the extra tab really helps plane off quicker - they will look extremely long when you first put them on, but they do the job. Need to be careful with deploying them too much running at speed, but I typically run my tabs and 1.5 - 2 most times. I found mine in the classifieds for about $500.00 in perfect condition. Incidentally, we tried the larger tabs on a friend's 27 w/ a 502MPI with similar planing problems and it worked well there to.

Well,

It looks like all the usual suspects are back on the site....
Welcome back Steve ......
and Hello Gary .....

You seem to have all the info you need ...

Just some info I picked up from Vinnie at Mariner's Cove Fountain ,our NY Metro Fountain Dealer...631 283 7001

It seems that all the 29 Fountains leaving the factory are having aeration holes drilled thru the collar of the props..

Vinnie says that Fountain found that getting some air to the blades allows the hull to plane quicker and cruise at less rpm....

Give Vinnie a call if you need info, He is very informed and knowledgable..

Dirtlawyer,

Was it easy to swap out the tabs for the larger ones?

no problem at all - takes about 15 minutes - all the mounting hardware is the same.

hears one thing you mite think about ,i kinda had the same problem . and was told 300 hours, i had week value springs and not want belive. so called crain cams and they said why yes of course. so i changed them in the boat with out pulling the moters. and hello,,,, 5400rpm this was a 96 mod hp 500
