do the 290 DP's have an impeller in them like OMC's 800 and Mercs?<br /><br />While draining the engine and hoses yesterday, I found a big thick main hose coming from the outdrive which led to the pickup holes on the front of the drive. I coudn't put my muffs on, and they're round, and couldn't adjust for the volvo intake positioning, and now I'm wondering if all I had to do was hook water to the intake line I found, that goes to what seems to be an impeller on the main camshaft pully. Any knowledge on this would be appreciated, thanks
