fitting I need for this?"
Can't help you with the fitting issue but I wouldn't think the flow volume through the filter would effect the high rev issue on start up. If it is not a cable or linkage problem I would suspect a high pressure pump / governor problem. As asked before, did the engine ever run properly and has there been any recent work done on it?
Thanks for the reply. We just checked the cables and linkage and they are fine. It is all attached and has the right "travel." The engine has run properly for the last 1.5 years we've had the boat and 200ish hours of use. The only thing we have done to the engine recently is change all the fluids and oil filter, which it worked just fine after. Then I went to change the Racor primary and the on-engine secondary filter, and once I got the new filter base and filter installed and re-primed this happened. So...I believe it to not be a random problem since it was working fine right before this.
