Bypassing Mercruiser 5.7L Shift Linkage

I am currently undergoing an engine swap from a 5.7L Volvo Penta, to a 5.7L Mercruiser Engine. I have a question regarding the shift linkage attachment on the MC (PN: 99236). My boat's current shift cable is a direct line from my throttle all the way back to the SX Cobra outdrive. The throttle cable hooks up to the side of the carb. I will have to completely bypass the MC shift linkage (which has a switch and some cables running to the other side of the carb). What does the switch on this linkage do, and what would happen if I completely bypass it? If I am not able to do this, will I need to swap in the carb from my Volvo?

Thanks!
 
You are keeping the volvo sx drive ? If so take the mercruiser shift plate off and put the volvo throttle cable direct to the carb . You may need the throttle bracket off the volvo.

the merc shift plate with switch is the shift interrupt used with the alpa one dog clutch.

Ayuh,..... What you should be doing is stripping the merc motor down to the long block, 'n putting All of the Volvo accessories on the long block,.....

What yer doing is well beyond halfazzed,....

I disagree... I've been running a stock crate 5.7MIE Mercruiser in front of Volvo 280 drive ( admittedly my boat uses the extended Hollman-Moody type housing to the transom with a standard bobtail bolt pattern) without any issues since 2008. The MERC accessories, i.e. exhaust manifold, elbows ( dry joint) etc. are better than Volvo's. The ONLY thing Volvo I would have liked was the Volvo raw water pump, however, there wasn't enough room in front of my engine to mount the Volvo raw water pump. The aftermarket Full FWC is superior to the Volvo block only system.

Thank you for providing additional details about your specific setup. I'm looking for a website where I can easily get some guidance on literature review-related matters. This link https://elizabethanauthors.org/ was sent with me by a very close friend, and I believe it to be really helpful for people like me. You can look into it as well, and I'm sure they'll offer the best services.
Yes, I agreed with you.
