Hi all from NZ
New here, please advise if anyone knows if a Quicksilver 48 16690 a 40 20p is suitable for a Mercury 75 HP (2 stroke)?
Hi. As far as I know, that’s the old quicksilver laser 2 for the smaller gearcase. Usually around 75-125hp 2 strokes in general terms.
Don’t quote me, but it should fit…but my word of caution around it being a 20”…might be to make sure it’s going to be ok for you. Unless you have a fairly light small boat with a hint of performance about its hull…it may be verging on too much pitch for your 75. Anything more than a boat like the above is pushing it really.
It depends on what particular 75 you have perhaps, but I can throw a comparison at you.
I had a 16ft fletcher speedboat. She had a 90hp mercury from around 1996-98. As far as I know, the 75 from around them may have a similar ratio to the 90. The fletcher hull is a fairly fast hull. Weight was around 400kgs or close dry and no engine. I had a 19” stainless on that set up. It may have turned a 20” laser…but with the 19” it went well and in the rpm range at around early 40’s gps any given day. Like I say…that hull was a quick hull with a little heritage in her dna.
So think about what you have and with less power…just to make sure you’ll be ok. Just thought I’d mention it. All the best
