I've been using the Pela oil extraction pump since this year. It's super clean and quite easy to use. Make sure to warm the engine up properly; then the oil flows more easily through the thin line.
Good product. However, I made some modifications using Teflon pieces to prevent the handles from rotating completely, thus protecting the seals and preventing water from seeping through the holes in the polycarbonate.
Unfortunately, one of the mounting bolts was drilled incorrectly. Raymarine offered no assistance whatsoever; the bolt could only be installed by omitting the provided washers. Very poor quality for the price.
I have a Bavaria Cruiser 37 from 2001. I bought a few of these mechanisms to replace on my boat. Put aside the quality that looks questionable, the item is totally different from the original locks. Basically the old locks were much bigger and as such I couldnt find a way to use the new locks. As original are far bigger, the location of the hole is much further away from the edge of the panel it should close. The only way to use the new one is if I would drill new holes in addition to the old ones.
