today i was out on the boat and after riding for about 2 hours i went to WOT and the boat only got to about 4800RPMs. it normaly goes to 5250. what could cause it to do that? i have the Monsoon 340 with Catalyst. thanks in advance for any help.

My obvious suggestion might be a different load on the boat? If it was running solid and strong up to 4800 or so, did you have ballast full and/or more people than usual?

You run it up to 5200rpm? Mine (04 HH) will hit the rev limiter a tad under 5100rpm...it has the 16 pitch prop, so would otherwise probably over rev.

Just a thought...

MIne is doing the same thing. Mine has a rough idle also. At 4800 mine is cutting out and falling on its face. The dealer told me that its probably the coil or computer, well see.

You can attach a fuel pressure gauge to the fuel rails Biggrin.gif
