speedo or GPS? very curious because with my boat I'm seeing just a touch over 60 with a 23P rev 4 and another mile or 2 more with a 25P mirage plus. GPS, speedo is about 5 higher but thats good for telling everyone speeds when they ask

2001 checkmate zt280 496ho bravo 1 24 and I've seen 68.2 with just me and a half tank. Full tank and a passenger and it runs 65ish. Needs bow lift I might send the prop out to get worked.

My other Checkmate: 1997 Checkmate Pulsare 2400 Bowrider, Mercury Verado 300 Pro, Bravo One 24, Atlas 8" hyd jackplate; 70mph GPS.

GPS recorded speed of 75.5MPH @ 5900rpm last weekend with my 2800SX Outboard. Merc 250efi's, 25" of setback, Bravo One FS 28's!!

What's a typical 98 251 w/502 MAG rated at 430hp run normally?

I would say the boat should run in the high 90's with 1600 HP. I hope you have hydraulic steering!

If your setup is good I think you'll be over 100. My old 30 was over 100 at 1300 hp.

Hi- considering picking up a 86 Enforcer 240 and would appreciate any comments you might have as to the boat's pluses and minuses- thanks- Doug- Maine
