BigA Posted March 30, 2022 Share Posted March 30, 2022 here is an interesting one for you all, just acquired a Sealine 285 with Volvo Penta AQ205A engines (petrol), one of which has a leaking sea water pump. i have sourced a replacement but the original has now been replaced. Looking at images (i haven't received the pump yet) it looks like the 3 bolts holding the pump tp the crank flywheel will need to be shorter, so, do any of you kind people know what site thread the cap head socket screws are please? i can add photos if that helps? cheers in advance.

Smoggy Posted March 30, 2022 Share Posted March 30, 2022 Being a volvo likely to be metric, I think they use the standard pitch on most threads. Quote Link to comment Share on other sites More sharing options...
NeilB Posted March 30, 2022 Share Posted March 30, 2022 If you ordered the replacement from a Volvo Penta dealer they should also be sending the new bolts, they are part of the replacement pump kit. If not they are p/n 948324 Quote Link to comment Share on other sites More sharing options...
