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:)

No pumps in the drives, all raw water pumps are engine mounted on Volvo's

Don: so then I can run the engine with no muffs on the outdrive, as long as I turn the engine off before it overheats? I'd still like to fog the engine correctly. I already spayed the fogging oil in each cyclinder, and down the carb without running it, but not sure that's enough. Also, without running it, I didn't get any of the gas with stablizer in it to the carb. <br /><br />Rodbolt: thanks for the tip, as there is a power steering cooler there, which is why I discovered this water intake line when I was blowing that line out to get all the water out:)

No, don't run the engine without water. Dons point was that the leg doesn't have a pump - the pump is engine mounted. You still need to connect muffs or connect into that hose you referred to. I know what you mean about a loose fit with the muffs but thats normal - water sprays out from the edges, don't worry. If you run the engine without water you will fry the raw pump impeller in seconds.<br /><br />Aldo
