please help
Hey guys. I'm new to here so first off hello.
My question is I have a 1979 175hp blackmax. I am changing out the center section for a 1993 model. Mine is 20" with 5" adapter. The 93 is 25". I believe the power head may have been replaced at some point. How can I identify if it has and with what year and/or size. The date on the side of the block behind the timing trigger is 6 15 8. Is that June 15, 2008? And the block casting number 858-6283.
My next question is which exhaust plate should I use? Should I do any mods while into the exhaust tube? I'm new to this and on a very limited budget.
I am curious if this is 2.0 or 2.4 and what will help it. I have a bayliner trophy 21 ft walkaround cuddy that we use for fishing and tubing. We have taken it to the beach once and ran it in the bay. It runs 39 by gps in saltwater with two ppl and 36 with two ppl in fresh. Thanks in advance for all your help and input

picture of power head will tell.. probably built '78 but could be an 80's something.. 99.9% gonna be a 2.0 motor but if it is an 80's something it will be a 2.4.. use tha plates that go with it... it may be tha block that has tha big hole, ugly exhaust.... not anything worth tha money ta make it any better...jmo

Is there a serial number on the welsh plug (freeze plug) on top of the motor, behind the flywheel?
