How would you advance the timing on these would a timing light work as far as milling the head is that measurement from the bottom of the dish were the spark plug goes to the deck

Ok do you know sst 45 spec
Is there any way to adjust the timming accurately I'm assuming it would be better to mill the head to sst 45 spec thanks for the help

I know they made some 50 hp commercial motors that have large gearcase but I don't know if mid section is the same
I have 99 40hp johnson with small gearcase lower and was wondering if I could put a large gearcase on it for more prop selection if not I need a small gearcase lower cuz mine is toast
I have the 50 hp carbs and boysen reeds on my motor the other things that were different was the head carbs and exhaust tuner
Ecotrons make a 2 stroke fuel injection kit and can be used for boosted applications it's 500 dollars pretty sweet lookin setup look it up
What mild mods are you talkin bout only other thing I know would work is put a 50 hp head on and shave it thanks for your help

Just me in the boat weights 650lbs. it done 33 mph @ 5750 rpm with a total weight of 1150 3 others in the boat
Did a test run today 50 hp carbs really helped out and I raised the jackplate 2in @ 6000 rpm it runs 35 now I'm just waiting on a prop I have a 12.25x15 goin to a 11.75x19 so hopefully it will break...
Thanks for the part number I finally found it earlier this morning I come across a stiletto triad 2 in a 11.75x19 stainless prop for $208.95 at firstchoicemarine.com
I just got some 50 hp carbs and the part number on the intake is the same for the 40/50 for the preformance gain that the tuner will give it's not worth it to me to pull the power head right now...
With the 12.75x15 I'm turning 5750 rpm so I think the 19p prop would be good if I I'm not satisfied I'll get it worked from my research they do not make a 21p prop for a small gearcase the biggest I...

How would you open the exhaust tuner I not wanting to take the power head off to put a 50 tuner in I've heard of drilling some bigger holes were the exhaust come out above the cavitation plate
I've also heard of adjusting the timing to get a little hp
Dose anybody have and info bout making a 40 a 50 or 55hp I know the carbs and reed cages are different I'm not sure about the head or exhaust I put 50 hp jets and boysen reeds in it and I'm not sure...
