  1. Hi, newbie here. Just purchased my first boat, a 2017 21 H2O Ski & Fish OB. We went with the 150HP Yamaha. Supposed to be ready before Memorial weekend (I hope!). It comes with a stainless steel prop. We'll be using the boat to pull tubers/skiers, fishing, & general cruising with the family. It will be used at our cottage on an inland lake, which has a rocky bottom. Wondering if a switch to an aluminium prop would be a good idea? I realize I may be sacrificing some performance, but if I run the bottom, I'd rather ruin a prop than the whole motor... What do you guys think?? Appreciate the advise, & can't wait for it to warm up here (Michigan)!!
  2. So, yes, I get it... the proper propeller question is probably the most asked question on any boat forum. But... I'm still going to ask it. What good is a boat forum without a virtual cornucopia of screw threads? Everyone loves to ad their 2ยข (I've got a mac, so making the "cents" sign is as easy as pressing option + 2) to the prop threads. First, my current boat specs: Year: 1998 (I was 15 years old when this boat was sold) Make: Chaparral (what else would it be on this forum?) Model: 2130 SS (Limited Edition - I think that got you some faux wood trim, a compass, and a depth sounder... how does that make it "limited"?) Length: 20' 6" Beam: 8' 4" Engine: GM 305 V8 w/ Throttle Body EFI - 240 HP (Yes, I would love for it have the 350 V8... no idea why the previous owner skimped on the motor...) Stern Drive: Mercruiser Alpha One, 1.47 Drive Ratio OEM Weight: ~ 3150 lbs Current Prop: Mercury 21 Pitch Aluminum 3 Blade (don't know the diameter) And the current Performance: Full Laden Specs - 6 adults: ~ 1020 lbs Gear: 100 lbs Full Laden WOT Engine RPM: 4,800 Full Laden WOT GPS Speed @ 4,800 RPM: 45 mph Minimum Laden Specs - 2 adults: 350 lbs Gear: 70 lbs Minimum Laden WOT Engine RPM: 4,900 Minumum Laden WOT GPS Speed @ 4,900 RPM: 49 mph Here's the condition - I mostly travel with 4-6 passengers in the boat and I prefer to cruise on plane, but at the lowest speed I can maintain on plane while still maintaining an efficient cruise speed. Furthermore, wakeboarding, tubing, and skiing are inevitable on a lake outing; being able to maintain a good holeshot/plane-out time with 6 people in the boat is a necessity. Yes, a bigger motor would be wonderful, however, my current motor runs like a top, so it is staying as is. My boat did come with a stainless steel 21 pitch Mercury Vengeance propeller that was a bit chewed up. I had it reconditioned and installed on the boat yesterday, but I haven't had it out yet. I have no idea what to expect in performance compared to the current prop. I've been considering the Mercury High Five as it comes highly recommended for this type of boat and intended use (and I have a wonderful source to get it quite a bit a cheaper than current market price). I'm also wondering about the Revolution Four. Are there any other props to consider from the other propeller manufacturers? Everyone seems to recommend a pitch, but no one ever comments on radius/diameter. I would imagine that diameter has a substantial effect - is it something to consider in addition to pitch?
