Rinker Captiva 262 SS performance ???

[HardmanGT]

I recently purchased a pretty rare boat and finding specs or even articles has been pretty tough. The few blurbs I have found online have pretty much come from searching here. http://www.offshoreonly.com/forums/general-boating-discussion/19197-new-rinker-performance-boat.html
I am hoping to get some info from you guys.

2002 Rinker Captiva 262 SS, 496 MAG (base) Bravo 1, 1.50, 15.25X24 4 blade Bravo 1 prop. 4800 pounds empty. The engine seems strong and runs smooth throughout the rev range. Whole boat has 40 hours.

From what I see, this boat should run at least 60 or better. My best has been 51 on GPS at about 4500 rpm. It acts like it's over propped in my limited opinion. I'm not sure if I am down on power or this boat really isn't as fast as I have heard it to be.

Does anybody have thoughts on this?

PS-my buddy was out yesterday with hos Baja 272 Islander 502, 420hp. With his labbed prop he is hitting 72-74 on GPS. That boat is even heavier than mine.

It just seems to me like there is a problem

I have a friend that has that same engine in his 28' Sunsation, he'll do 65 gps with it.  Doubt that it's lighter than your 262.  How about a tune up?  Maybe you're running on 7 and not 8 cylinders.  My '96 232 sounded fine, planed fine but had no top end.  Found a cut in a wire and it was arcing to ground.  Replaced the wires, plugs, rotor, and cap.....BIG difference.  That has the 454 with the B1 drive and a 23" Mirage 3 blade prop on it.  No way you're overpropped, not at 24".  I think with that power you could swing a 26" on there.

I replaced 7 of the 8 plugs today (last one required some bracket removal for access, didn't have the patience today), new fuel filter and separator. Tomorrow I will check the wires with a multimeter and timing.

I also found that the idler pulley is on it's way out and throwing off a fair amount of fine black plastic around the front of the engine. This also includes throwing it into the flame arrestor where it is being ingested into the throttle body and intake.

I have ordered a new idler pulley and cleaned out the flame arrestor, throttle body bore and blade. Could this stufff have gotten elsewhere and be causing a problem/restriction?

Remember, you have a base 496 which is 370 hp  you are turning proper rpm, 4,500 is correct.  you could bump up to 4,700 but that is it on the base engine.  Most were set up with the HO 425 hp and some have the 525.  The 496HO should run just at 60mph and the 525 is just under 70 mph.  Heavy boat, hull is similar to the fastest hull prior which was the 236.   Al

The 262 is right around 5,800 > 6,000 lbs.

Boat tests had the small block version running at 45 mph, 496 would get you up to 54 mph.

Best I've seen on our 276 was about 54 as well.

You're not far off. 4,500 rpm is correct as well.

You've probably got a pretty good boat on your hands with only 40 hrs on it.

  I want to make clear that this is not a standard 262, There are no sinks, refrigerators, tables etc. This is an SS and was only produced in 2002 and 2003. The email returned from Rinker states that it is 4800 pounds.

Nice boat!
I'm leaning toward agreeing that you might be a bit over-propped for your boat. I had a couple of the 236's both with the 454 (300 HP) Merc engines and the Bravo 1 drives. Both boats would run 60 plus at around 4800 - 4900 RPM using the Merc Mirage 23 pitch 3 blade props. My 1990 236 would run 65 on GPS while my 1994 236 would run 61 on GPS. Both had switchable exhaust but that didn't really make much of a difference at wide open throttle except it sounded cool :-)
The four blade prop will give you a better bite on the water when taking off but will also create more drag when running on plane. More blade surface in the water at any given time = more drag but better bite and less chance of blowing out the prop while in turns, etc.
