got a 87 115 now,run across a 83 150 black max with 50 hrs on rebuild,sit last 2 yrs,i can get whole ski boat,tanden axel trailer,trol motor,extras for 1500,,,would this 150 be noticably stronger than my 115 with maybe 15 hrs on it??
on my rings,i put the new 2 ring setup on and noticed the bottom ring when lined up with the little pin would stick in the groove when i pushed it in hard by hand,so hard in fact i had to use a knifeblade to help pry it back out,i tried both rings on the bottom,same results,so i got some 600...
how or why would two motors same size use a high or low,,2 or 3 ring setup,does the highdome have more compression,,is the 3 ring piston preferd for better sealing?
need a rod-rod bolts-stand rings-main bears-complete powerhead gskt seal kits-rod bears- for a b197312 motor,,,,,seems the newer stuff easy to find but mid 80s,,,,tried a few searches but no rod found yet,thanks.
mercury 115 serial b197312 elpto would like to if posable upgrade just the powerhead to the next size that would be compatable with lower unit,,,anyone with knowledge on this? also who would you recomend if it was yours to buy from?
