I would call them. I would ask if you could email the pics of your dash and then ask to see if they can get you part numbers. they may give you part numbers and point you toward a dealer (such as Iboats) to make the transaction.
casting numbers are only part of the equation.
they should be 0.341 or 0.343. the LS motors use 0.315
your heads could have been worked on prior.
I would talk to your local machine shop. you need to cut the seal seats, and I would seriously upgrade to better seals and screw in rocker studs...
you call the customer service desk at sylvan and go thru sylvan. Just understand, they may not exist in the specific configuration if they were not engineered with that face series, pointer series and blue back-light
Even I cant buy those proprietary gauges because of the business agreements...
Uhhhh.....VeeThree.....just like the tag says.
99% of what VeeThree makes is custom for OEM's and is not in the catalogs. the only ones in their catalogs are the ones they sell thru Sierra. Of their custom gauges, some say dolphin, some say some say honda, some say yamaha, some say searay...
If you had your drive off, I would say just fire it for a second or two
or simply pull the impeller and fire it for a second or two. pulling the impeller on a cobra is much easier than on an Alpha or stringer
If you cant drop the drive completely, you may be longer than you think To put my searay in the garage, I had to back the trailer up on ramps to be able to drop the drive completely. That was only way to get the boat backed in far enough
I have purchased from USC in the past. however I now have an account at FGCI since its near work. much cheaper to buy from a large local source than ship.
I would try Northern Composites in Hampton NH
otherwise, expect to pick up about 10 gallons of resin alone plus your CSM and 1708
