Dream 'Inn III -- 2008 400 Express
Thanks to all who have responded to my query regarding impeller replacement. This is my first Rinker, which I have only had since tuesday. I've owned other boats in the past, but access was always easier. This particular 246 Captiva I have is a 2007 model, and I have searched, in vain, for the above referenced removable floor panel. This deck is a seamless glass construction where the lounge seating forms a bulkhead in front of the engine. I would have to take out the removable cooler, then take a rotozip to cut a large hole through the bulkhead to get any better access to the front of the engine. I'm not keen on this approach! It seems the only solution is to try to squeeze myself down along the starboard side of the engine and try to get at it that way or else hang upside down! How do the certified service techs do it? Thanks again.
OK, thanks Al,
I won't attempt to tackle this until you post what you have learned. I did manage to get down in there to get the lay of the land, as it were, and I have discovered a large rectangular casting, resembling a big black brick, under the alternator which has what I believe is a fuel line coming into the front of this unit from the fuel tank. There are two hoses going into the back of the unit that are apparently just pressed on (no hose clamps) and on top of this unit there are what appear to be some sort of service access covers, screwed on. The forward one has sort of a handle on it and the rear cover is kind of an inverted pan-like dome with an electrical connection on top. I cannot identify a pulley driven pump housing unless it would be buried under this brick & alternator and thus virtually impossible to get at. The engine sits very low in the bilge deep between stringers. The fuel tank is maybe a mere 2 or 3 inches in front of the serpentine belt and crank pulley ,etc. For something that is recommended to be replaced each season, it seems like a poor location for the raw water pump! Or they could have made an engine hatch cover more like on a Crownline or Chaparral, that exposes the entire front of the engine.
nice vid.. but the 2 piece raw water pump is a little different. No long bolts for one thing.This one looks a little more like what I have in my 05 270. I need to pull the bracket etc similar to this video.https://www.youtube.com/watch?v=eZYJq746awc
Ok, the job takes no more than 3hrs start to finish. We just completed a 246 with a 350 mag
1st remove the **** pit seats and bases as well as the back wraps.
2 Remove the removable panel located directly in front of the motor
3 The convoluted foam will need to be trimmed to remove the fiberglass panel
4 Remove the hatch ram struts and use a long pole as a prop to open motor hatch higher
5 At this time you will need to be in the motor compartment as well as in the cockpit working back and forth
6 Remove the belt assy, pay attention to which direction belt is running
7 loosen hose clamps and hoses from sea water pump
8 Remove bolts for sea water pump
9 once pump is on the bench disassemble pump and replace impellor
10 Reassemble in reverse order.
This engine does not need to be pulled to service this pump. We intergrated the removable panel to allow for such access during prototype stage of the 246.
Good luck Al
Thanks for the tips, but you're going to think I'm some kind of nut! I removed the "J" shaped seat back that forms the cockpit lounge and unhinged & removed the seat cushion over the removable cooler. I got real excited because there was a panel section that is held in with screws. OK, so I took out the screws and lifted off the 30"w x 17"h panel that only goes from the top of the backrest down to only about half way to the floor. Guess what? Solid glass behind! Apparently this panel just fills in a recess in order to make it flush for the seat back cushion. Is my 246 an odd ball, one off?
Once the panel is removed, you should have access to the front of the motor. If this is not cut out from the factory, someone skipped a position and covered it up with foam. I really don't have any photos of what it shold look like. Sorry. Al;
I will attempt to post these pictures I just took..
#1 Cushions in place
#2 Cushions removed - panel visible in upper half
#3 Panel removed
No access panel to front of engine. So what gives?
