Hi All, Thanks for all of the replies. I replaced the fuel filter and all fuel lines out of main tank. Took it out and pulled 5400 rpm at about 32 knots. Changed prop back to 17 and pulled 5800 and roughly same top end. Cruising speed at 4500 is 21-23 knots. Very happy with this. Not sure how it will go on the fuel but will find out in due course. Thanks again. I did not think I'd get anything like the top end I've got. Also putting some trim tabs on so will see if that are differences out of the hole.

Hi All, I'm a little stumped. Transplanted Yamaha F100D onto Reef Ranger bought recently. All set up properly as far as I can tell. Dropped into water and can only get 3200 rpm out of motor. The boat came with 160 liter tank. I filled tank with 100 litres thinking that any problems with fuel would be diluted. Filters all look clean. Tank breather also looks fine - has canister fuel/air separator on it. The Cav plate on the motor sits at level with bottom of pod although that is 50mm higher than bottom of keel. Thinking about hooking up small fuel tank with fresh petrol to see what happens. If anyone has suggestions they would be very much appreciated. One person suggested it was a prop issue but I find it unlikely that a prop issue (has 13.25 by 19 standard Yamaha on it) could cause this much problem. Over to you....

Thanks Blairy. I'm happy just pushing along at 20 knots so I'll see how she goes. I'm in Cairns so the reef is pretty close and the 4 stroke should be pretty economical.. time will tell

Hi All, I am thinking about powering an older Reef Ranger with a pretty new Yamaha 100DET 4 stroke. Some say it will be sufficiently powered while others suggested a 150 at minimum. Would love to hear opinion from others who have been in a similar situation. thanks, Jeff
