Hey Spare ?
my 250 Wellcraft had OMC auto primer pumps and they aren't working quite right where or what do the newer boats use or have for primers in place of the hand primers? can you use a 2.5 to 4 lb 12 volt fuel pump in line under deck or in the transom pass box?
can you use something like this inline? http://www.jcwhitney.com/universal-s...23&zmap=738895  something like this is inline currently on both motors from the old OMC Sea-Drives http://cgi.ebay.com/ebaymotors/MARIN...item35adb18999 or http://cgi.ebay.com/ebaymotors/MARIN...item483d2385d3

Skools, I don't see any reason you couldn't use those, but to be honest, I'd leave them out and just hook up regular primer bulbs(use johnrude bulbs, they're the best for the $). repalce the anti siphon valves with new ones, that will keep the fuel line from siphoning dry back in the tank, and put the bulbs between your water sep filters and the engine. You shouldn't have any problem with it. We ran a simular set up to feed Merc XRI motors on high performance set ups, but it was to assure it wouldn't run lean on top end
BTW, check you pms

btw, what mpdel seadrives were on that thing, we used to sell them in Raleigh on Proline boats, i can't remember any of teh ones we had having electric primer pumps. i know the all v8s(seadrive, johnson, evinrude)came with them, but i don't remeber any of the ones we sold having a primer pump. DO you think some one added them?

i guess they could have offered them as an option, I know they were standard on teh V8's. Only concern about those pums is meeting USCG requirements and if they are corrosion resistant. Could use the low pressure bosch style pumps like they use on mercruiser carb I/Os

since they weren't set to run all the time should they have run only like 30 sec to prime before starting then turn off to crank and run without using them? i've never seen this setup before.
