Hey guys this post below accually almost aplies to myself. http://www.iboats.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topic;f=24;t=003719 <br /><br />My new motor will not rev over 3300 rpms. Im sure tach is dead on cause when i rev her out of the water she will rev to 4 grand very fast. I try not to do that much cause she only has baout 9 hours on her now. I have only been cruising between 2600-3300 rpms anyway which is 30/32 mph per gps. The hole shot isnt very good with 4 adults in the boat but will get up in about 6 seconds. <br /><br />Sunday while we were comming back in threw the pass there were solid 3-5 footers and the boat had trouble reving up in that slop. Again we had 4 adults on board. The motor did sound like it was straning more then she should so like the previous post im wondering if some bozo put a v8 drive in my boat. When i got the boat the drive was laying on the deck of the boat, the prop has no #'s on it. Can a prop shop tell me w hat pitch/diamiter prop i have on there now? Tomorrow i will open up top of drive and count the teeth. How many teeth should i have for a 3.0 L Mercruiser and how many should there be for a v8 Mercruiser. <br /><br />Thanks in advance guys, <br /><br />Big-E<br /><br />BTW. the boat is running great and we got her nice and bloody on sunday.
