- Was 310 HP MPI --> Twin full 454 Mer-Cruiser 400 hp "Gas Aspirated" Less to worry! Works for me!
My props are like new currently and they are in fact 17 x 19. I plan on doing some extended cruising of the great lakes and would like a set of spare props. These will get me home and to your point work fine... I just got the boat a month ago and with the bottom pretty dirty from setting around for a couple months it hit 4900 rpm... I could always get them re-pitched back to 19 if needed. The boat has been hauled out for the year so I plan to freshen up the bottom, Have my props checked and then next summer figure out whats the best. Lots of different opinions here. For now these are a great set of spare props in case I decide to chew up a log. The tabs on the 34 are ridiculously small so you tend to run faster than than you want. I have the extensions all drawn up and ready to build once I do a couple measurements with the boat out. I think the boat will then cruise down around 3200 RPM vs 3400 to 3600. Maybe lower with the 17 x 20 as long as it doesn't load up the motor. 1" of pitch is typically 200 to 300 RPMs. Thanks for the heads up...
You may want these and will work much better: Brand new SET of TYtorq 18"x22"x 1"1"1/5"Shaft , Light Cup MY-T3 Used for a 370SDA ---- $650 + Shipping. Leydenjon@yahoo.com
