New in package, replacement impeller for 4-8 hp Suzuki outboard motor applications as detailed in the chart below. I am even considering smearing the shaft with flexible gasket sealer and letting it set all winter hoping it dries and forms an exhaust proof seal.Water Pump Impeller for Suzuki 4, 5, 6 & 8 hp Now that I know about this blind install, I am going to do my best to carefully install the lower unit with perfect alignment, and pray for success. You cannot see to line this tube up with the pump when reinstalling the lower unit, and I’m betting this is why the pump quits working when a new impeller is installed. I really think this may be more of an issue than the oil seal for the top of the pump housing. Suzuki calls this – The water Pump Case Grommet Part#- U28 Genuine Suzuki Marine 17415-98501 Water Pump Case Grommet. This one “seals” the water line going to the motor, where it goes into the pump. While replacing the seal, I spotted another rubber gasket. Since the seal had broken down from either heat or water abrasion or both, I suggest buying a tube of lithium waterproof grease, and coating the “oil” seal when you install it. But so as not to confuse lets call it the Oil Seal. Technically it’s not an Oil Seal since it seals the shaft and prevents exhaust gas from pushing water out of the pump. It’s a - R91 Genuine Suzuki Marine 09289-10002 Oil Seal. I went to the Suzuki Part page, and found the seal. I finally found another owner who said he replaced an oil seal on the pump head, and that fixed the problem. My motor is 1992 vintage, but from what I read the DT4 had this problem for ten years with no recall, or instructions for a fix. Sooooo – Suzuki knows about the problem and has no recall, no fix, and only an exasperated tech who tells customers to drill holes to relieve the back pressure. I found another forum post where the owner had contacted Suzuki, and the tech acted like”I’m sick of hearing about this” He told the owner to drill out the relief holes at the back of the motor at least two sizes larger and the back pressure would be reduced enough for the pump to work. NOTE: the pump would work when the access cover was off, because the exhaust vents thru the access hole with the cover off. I read several forums and the consensus was that the exhaust from the motor was pushing the water back down the tube, and the pump would run dry. Took it off again and it started pumping. I put the access cover back on and it quit pumping. I forgot to put the shift linkage access cover back on, and the pump worked and was pushing out of the telltale hole nicely. I had meticulously followed the instructions for changing, and rotating the shaft clockwise while bringing the top plate down over the new impeller. The first thing I did was order another impeller from a different seller, and made sure that it said Genuine OEM part. I have been having the problem where the pump stopped working after an impeller change.
