[FONT=verdana, geneva]Hello I started this thread in hopes of attracting some helpful advice. Picked up a Laser 2 prop 20 pitch and just ran it for the first time with the vent holes open. Also had about 320 pounds of extra weight on board for today's test which is NOT consistent with my other prop test runs (me and one other person) so I will re-test again as also the weather was against us today.[/FONT]
Long story short, prop turned 5000 rpm and was slowly gaining some speed as it kept going, problem is the hole shot was the worst so far out of all the props I tried. The previous 3 props I tried were all aluminum, 17, 19 and 21 pitch. All ran great with good speed, but the 21 had terrible holeshot, though it did give me great top speed (48 MPH on GPS) at about 5500 rpm. The 19 and 17 both got me out of the hole really fast, but they over revved my motor to about 6000 rpm. I would rather be propped towards the 5600-5700 rpm range that way if I have an extra person on board like I did today then I could hopefully be maxed out at around 5400-5500 rpm. And if I have my normal load, I won't let the rpms go past 5500. Is this the right idea??
So this is the first stainless prop I am trying, but why such a bad holeshot? Is it because I had the vent holes unplugged?? I thought the vent holes will allow the prop to spin faster till it bites?? Could it be that I am spinning too much and not enough bite, kind of like doing a burnout in a car? It literally took about 10 seconds to just get out of the hole, and it felt like it would never get out, but it felt great when up on plane and had a really good feel in the water, great handling and speed, even low speed/docking was improved.
[FONT=verdana, geneva]Overall I really do like the prop, but I am very disappointed with the holeshot. The top speed wasn't bad considering I had a lot more weight than usual, my gauge was reading 47 mph which is about 4 mph off (so more like 43 mph). I tried this prop in hopes of experimenting with the vent holes to see what kind of results I get. Should I try plugging them? They are the square type holes not the round ones and the motor is a '95 yam 115 V4 2 stroke on a 16.5 center console.[/FONT]
We hit some good chop in about 15 kph winds right against us and I was VERY impressed with how well this prop was holding the boat, in fact it handled so well that this was the only time I was able to run full throttle while going head on with some decent chop and man am I impressed! I will try it again this week as we are having a week of wonderful weather and I am 10 mins from the lake. Do I plug the vent holes and try again? Or do I take my prop to the shop and get them to work it a bit? Or should I just try the same prop in a 19 pitch instead?
