Tony,
Thank you for your help. I did not understand the performance curves and was reading them wrong. After reading the article you directed me to I get it now..
Thanks again.
Don

Tony,
I’ve been comparing the performance curves between 3 engines. I”m having trouble rapping my head around it.
What I’m having trouble with is when I compare the cruise rpm The QSC 500 at 2200rpm has 490hp with 1170ft-lb torque@ 15.7 gph
The QSL 450 at 1800rpm has 407 hp with 1188 ft-lb torque@ 14.5 gph.
Wouldn’t the QSC 500 push the boat easier because of the more Hp?

If I go with the QSC 600 at 2200 rpm 534HP with 1274lb torque @13.3 gph and ran it at 2200 would I achieve the same cruise with less load on the engine?
Another question I have is would the QSC be a smoother running engine at lower rpm compared to The QSL9?

Thanks
Don

Hey Rob, I have to have it built to my specs….LOL I still have the Albin if all goes as planned I will put it up for sale in the fall. We will definitely be at the beach hopefully alot and we will be heading to Essex but not for the rendezvous bad timing …

Tony thank you for the reply.
The TJ can swing a 28iinch wheel with a 2 inch shaft.
the suggested gear for the QSC 500 is TD 5065 A ratio 2:04
for the QSL9 the suggested gear is also the TD 5065 A 2:04 or a ZF 286 1:75
