boat is a 1999 larson escape 233 volvo penta 5.0gi sx-m outdrive

not to sound biased, but on the automotive version of this ignition system, you remove the pin c wire (ignition bypass) from the 4 wire ignition module and the engine will lower speed and you can set base timing, i have read a lot of different posts, and it pretty much boils down to needing volvos shunt, which goes inline with the connector and you connect to power, is there a shortcut? can i do as i would on the automotive version and remove wire from ignition module to put into base timing mode?

Here is the skippy on what i am doing, bad winterizing on my part, so i am installing a long block, going to be installing this week. expensive mistake, definately wont do that again

You have conflicting information there 99, a GL is normally carbed, and a Gi is injected.
Do you have the full model number or Volvo serial number for your old engine?

possible the plastics over the flash arrestor are from wrong item, i will get the serial #, but i know 100% that it is throttle body injected and a 305

This was given to me nearly 6 years ago, right from the Volvo manual. I used it on my Mercruiser with perfect results:

If you look in the manuals I gave you links to in one of your other posts, it explains how to set the timing.
