Hey all,
I need alittle insight as I am new to the boating world. Over the weekend I was invited to go out on my brother in laws boat ( 15ft Gemini ) and do some fishing. While going out on the boat I had notice when we cleared the no wake zone and we throttled up the boat just would not gain rpms and my brother in law went to the front of the boat and then the boat started to gain rpm and plane out. Being a mechanic myself I told him thats not right. He has recently put a new prop on it and I noticed it was a S/S prop and the other one was an aluminum. It seemed to me like he may have gotten the wrong pitch prop but he says that there's something in the prop that when if it hits something hard enough that internally something will give before it does any damage to the lower unit. Does this sound right ? I would think that if that were to happen you wouldnt be able to run in the water atall, but nonetheless it ran extremely well ontop with no vibrations once rpms were gained except for the fact it wouldnt come out of the hole for nothing untill the bow was loaded. Is there any way I could find what the proper pitch would be like an oem spec ?
Sorry for such a long 1st post but wanted to give all the info 1st shot.
