A while ago I saw in PBO a waterpump impeller cover that was removable without a screwdriver... it was brass I think and had thumbscrews instead of standard screws which made changing the impeller at sea in an emergency much easier.

Anyone know where I can get one of these? I can't find it anywhere in my 2 years back catalogue of PBO (now in the downstairs loo BTW!)
 
Agree... that's what I did... from memory I bought M3/4 S/S studs and a dozen or so wing nuts, just in case i lost one /forums/images/graemlins/grin.gif
 
I changed the screws to allen key type as there isn't much room to get a screwdriver onto the normal heads - works a treat for me.

Cheers
 
Speedseal an excellent bit of kit. Not only is it much easier to get on and off, leaving some of the screws in place so they don't drop in the bilge, but the seal using the O ring is much more effective than the normal paper gasket.
 
Agree with speedseal. Great piece of kit. Only downside was the impeller removal tool they send with it. Has anyone tried to use it??? No matter what I did it seemed completely useless and they don't give you any clues.
 
Part of the problem with impellor removal is that some of them are fitted with a screw through the impellor and shaft. To get at this, you must remove the shaft with the impellor. Whenever I do this, the connector behind the shaft gets displaced and the whole pump has to come off to replace it!
 
With little space between engine and bulkhead for a straight screwdriver, I did try swapping screw headed bolts for hex. head bolts on the Yanmars on my raggie cat. This enabled me to get a ring spanner on them which was satisfactory. But Speedseal is the answer that solves all IMHO.
 
Glad I don't have your type of impellor. Mine is a Johnson type with a pin through the middle of the impellor that fits onto the shaft via a deep ...er...groove. I still have to get a pair of grips onto it to remove though. That silly bit of plastic Speedseal supply is about as useful as a chocolate teapot.
 
Arny,
Just seen one today - Carol / Bob at performance yachts has a sample sitting on the bench at Mayflower Chandelry - it's been there for ages and I wondered what it was but today I realised exactly what it was
