Wedge Spacer for Carb???
I sat the motor down in the boat today and really noticed the carb angle with the new intake. It is a PCM alum. intake with the lined coolant passages. I would like to keep it if possible. Have not ran it yet obviously, just wondering if I should try it first or get a wedge spacer to correct it now.?? The front of the carb. is really low!?!?

Pleasure Craft Marine, PCM, most likely hooked to a straight inboard drive line in a cruiser. The angle would sit the carb level in that configuration. Probably your best bet would save the money of having a spacer milled and just replace the intake before you invest the time in rigging the boat. Shouldn't be hard to come up with a good small block perf intake.

That's what I was thinking too...He does have the lined or anodized version though. Weren't these used like on a mid engine mount boat like a Mastercraft ski boat? Thus giving the carb a level ride due to the location of the motor?

Also with boat in water , it may be slightly different. If it's a spread bore I have a few spacers. It looks like a Holley, and the best way to set the float level is with the boat in the water and open the sight plugs and adjust until fuel slightly trickles. There are 2 of these.
Pcm engines were installed mainly as Inboards and several manufacturers like Shamrock used them.
I've seen spacers made out of wood and arent too hard to make. You can start out by tracing a gasket and cutting the part out, and then sand it down. You would want to use a hard wood like maple or cherry for it to be durable. The spacer also isolates heat from the carb, in turn making air and fuel more dense... A 1" open spacer usually adds to top end performance from what I've seen. BBB

Moroso makes wedge spacers, I have used them on drag cars and helped fuel problems leaving the line. But I used them to tilt the carb forward. Just curious if anyone has used them on a boat to cure my problem. They are fairly reasonable. As far as the way the boat sits in the water, it is not going to change that much.
