Looks just like my '74 when I got it...even the '86 Evinrude 150...I had the exact same motor and it's a real workhorse...good power for that boat...only downside there is gas consumption...that is what lead me to up-sizing fuel tanks on mine...discarded the 20 gal saddles and constructed seat boxes to contain 40 gal tanks each side...total 80 gals...freed up lateral space in cockpit, too, plus the rear of the boxes are excellent place for rod-holders
Remade floor hatch-lids outta 3/4" starboard and found large cooler to be fish-box in forward hold...that has worked out great...
I've just discovered my forward deck in front of the windshield has gotten soft from wood core rot...while you have yours apart, check it out as it'll be LOTS easier to repair flipped upside-down...
One thing ya wanna do is when you put the cap back on, the panels under the dash-boards SUPPORT the dash...it's important to get those the right height so your windshield center piece fits...
Good luck and keep the pics of your progress comin'!!...
