Hi Guys I'm from the U.K

I have a viper jetboat fitted with a 120 sportjet and i want to convert and fir a mecrury 175 Efi engine, i'm told that this will fit on the standard pump fitted to the 120.

i have been given some part numbers that i need to get todo this conversion

830125A1
835367
20826

I'm told that the item called the cover assembly is a mounting plate that I need to connect the 175 engine to the 120 pump.......or do I need other parts aswell ??

can anyone help please ?

Unfortunately we do not have experience with those boats and converting to larger powerheads.
