Adam F Posted March 24, 2013 Author Report Share Posted March 24, 2013 I think I've found an Ali 4 blader in the size I need, for not too much money. I'm tempted to buy that and see how I get on. If it goes well ill consider flogging it on and upgrading to a new SS one. Rob 1 Quote Link to comment Share on other sites More sharing options...

Adam F Posted March 24, 2013 Author Report Share Posted March 24, 2013 OK thanks nige. The one I'm getting is a 14.24x19 so I'll how how that goes first. Have you got a 4 blader on Wishin II? Quote Link to comment Share on other sites More sharing options...

Adam F Posted March 24, 2013 Author Report Share Posted March 24, 2013 Can't you get one of the universal props ie. Solus and then the hub adaptor kit. Mercury (barrus) also do one. Quote Link to comment Share on other sites More sharing options...

Adam F Posted March 25, 2013 Author Report Share Posted March 25, 2013 Right, getting somewhere. Had a good chat with Coastalrides - who supplied the engine orginally. My D3 should max out at 4000rpm - it doesnt so, I'm over propped as I can only get 3600... so thats good news. He has also got a 2nd hand 4 blader that isnt much money - Ive bought it and going to give that a bash - if it works and I want to upgrade to a SS one he will take this one back in exchange, or if it doesnt work out, he'll take it back for a 20% restocking charge - sounds fair to me. Fingers crossed with a 2" reduction in pitch and an extra blade I should get more revs, a better hole shot and a better cruise. I'll know tomorrow as it will be here in the morning!

Adam F Posted April 13, 2013 Author Report Share Posted April 13, 2013 Finally got this sorted. Coastal rides sent me out the wrong prop last week, right size but was too short in the hub. After a lot of to and fro, they offered to do send me a new Volvo prop at a good price. So for the record I had a 3 bladed Ali prop 14.25x21" I was getting 3600 rpm. Max rpm for the D3 Volvo is 4000 rpm. I now have a 4 bladed Ali prop 14.25x19". I went out today for a short blast up the harbour, a full tank of fuel, Little Reub and a huge bucket of tools onboard. In summary it is a better set up but it will take a few hours of use in varying conditions to really get a feel for it. The old prop wasn't that far off, but with this new prop I feel I'm getting the most out of the engine, and the right pitching and extra blade seem to do what everyone said they would: hole shot seems faster, I'm now planning at much lower speed, just over 10 knots, I get lower revs at cruising sped, for example I used to cruise at 18 knots for 2800rpm, I now get the same speed at 2600rpm. I did give it a WOT run.... That was scary! I've never wound the engine up to 4000 before! It felt like it was screaming and I was concerned that I'd go over.... But nope, at the throttle stop I was bang on 4000 so that was good news - this gave me 34 knots! I've also got the benefit if having a spare prop to carry just in case. So really chuffed and I look forward to trying it out a bit more this spring. Stuie and niggle 2 Quote Link to comment Share on other sites More sharing options...
Jim Posted April 13, 2013 Report Share Posted April 13, 2013 Interesting thread. Tiddler is on the max engine size and hence a little stern heavy. I spoke to the designer / builder who said that trim tabs would get her up on the plane at lower speeds. I'm reluctant to start drilling and fixing tabs. I wonder if a 4 blader would help on a titchy little boat? If I get up onto the plane, and ease back to stay inside the harbour speed limit she begins to fall back off the plane. This sounds like prop slip. Maybe I should be speaking to some of these propeller companies too ? ? ? Jim Quote Link to comment Share on other sites More sharing options...
Rob Posted April 13, 2013 Report Share Posted April 13, 2013 Bloody fantastic Adam, more Alderney budget for tackle, rather than fuel!!! ;o) You needed some good news!!! Jim, you need tabs! Even a 40 would prob weight the same as your 50. I put tabs on mine and can happily plane @ 10knts, and more importantly keep on the plane, before it used to be 12/13+ if I didn't want it to drop off when encountering wash.

Steve S Posted April 13, 2013 Report Share Posted April 13, 2013 Good to hear you got a really worthwhile improvement. What was your top speed before? Quote Link to comment Share on other sites More sharing options...
great white Posted April 14, 2013 Report Share Posted April 14, 2013 about half a knot slower than ours Adam F 1 Quote Link to comment Share on other sites More sharing options...
Adam F Posted April 14, 2013 Author Report Share Posted April 14, 2013 about half a knot slower than ours Lol! It was a while ago that I tried, but I think it was 32 knots. Tab ah, I couldn't give a toss about the top end, I never use it, why would I, its the more economical cruise and lower planning speed that is the big benefit.
