Will a b&m 250 fit in a 27 fever?
 

Wanna buy a B&M 250 for you 98 27 fever with an hp 500 carb motor. I just wanna make sure that it will fit behind the back seat and won't hit the engine hatch. Does anyone have one on their boat. Any info would be great don't want buy one and have to do any cutting. Thanks

I have a 29' single with one Fits fine with top clearance
Pix are before i did circ pump delete kit that cleans it up a bit in the front

1 1150 domintaor = no cutting. 2 carbs or an initercooler = cutting. It had a small clearence cut behind the seat but not all the way through into the cabin. Mine was a 1992.

This may be a dumb question but can you still run captains choice.

My old '94 27. Just a little pulley clearancing, not all way thru. No hatch mod needed.

Had some motor work done by a machine shop owner that had a newer one, 97ish?????? and he lined the hatch opening edges with some AL sq bar stock to relocate the hatch higher to keep from hitting the air breather. The newer boats have higher x dim than the non stepped (pre 95) 27's, thus higher motor mounting.

My -93 have a 525SC, small pulley clearance behind the back seat. If I remember correctly the stock flame arrestor (10"X3") on the Dominator have about 1" clearance to the hatch. My propshaft is 4.5" below the bottom.

Thanks for the info guys. im gonna bite the bullet and buy one now. I really can't wait till summer. Just gonna have to figure out my prop size now.

This might help you to figure out if you have enough clearance to the hatch (page 12).

One of my friends has a 98 27 Fever (HP500) with a 250 B&M on top and it fits just fine. He runs a 28P LH B1 prop, 1.50 B1 drive (not XR or XZ). I think he has only blew 1 or 2 drives in the past 10 years. Boat runs 78 mph on gps any day (and remains stable). Biggest problem in his boat is chine walk ... it gets really bad. He can run faster (he is not maxed on RPM) but the hull starts jumping what seems like a couple of feet side to side and has to back out out of it. :eek: I'm not sure what "top speed" he has achieved. Another friend had an 509 cid HP500 copy in a 91 non-step 27 with a 250 B&M, also. That boat ran right at 80 mph with 8-9 lb boost. He was running a 1.36 ratio drive and a 23P (i think) Rev 4 prop. Never had any drive issues in 10+ years. He tried a Hydro QIV prop but it lifted the stern too much (it was very noticable) and the boat porpoised at top end - didn't do that with any other props we tried, and we tried a bunch :D

Mine used to chine walk around 70mph with Mach sterndriver prop 14X24 (4blade). Currently running a P5X and have not experianced any chine walking with this prop, only porposing in calm water above 70mph. Will try a -2 lower this summer.

Mine chine walked bad right around 74-75. Found it best to power right thru that area and it settled right down.

I 'think' I was running a 27" hydro, (been 9-10 yrs since) for a top end of 83

Our 1996 27 was a single step with HP500. Top speed was right at 76 mph, but you could not run it there because it would have thrown you out of the boat due to chine walk. At 74 mph with tabs level, it was ok but as you got to 75 - 76 with throttle and very slight change to tabs, it would start to walk a little bit, but as it climbed just north of 76, it got violent and you had to get out of it .... didn't have any more "power", though, to power through it :rolleyes:. :D

Jerry, the 91 I was referring to belonged to Charles .... he borrowed one of your QIV props to try, many, many years ago.
