    Re: Suzi 140 07 owners

    Just an update, Trialled another prop on the weekend, the turning point, haven't been able to get hold of a 20 pitch Merc prop as yet, might see if I can ring another dealer tomorrow, any suggestions of a merc dealer on the south side?

    The TPP prop really laboured the engine, and went no where near redline.
    by the way falls of the plane at 24 kms. Have got to say, there doesnt seem to be anyway this engine is able to swing the 21, I would be frightend to cross a bar with it, particularly around the amount of time it takes to get the boat on the plane. I have another solas to try, 3 blade but wont get to it to the weekend.

    Geez, suzuki must have made crap 2 strokes.
    No wonder they stopped.

    I was just making an observation that it a manufacturers 4 stroke blows away their equivalent 2 stroke( although some of suzuki's HP rating's are debatable)then might be time to give up....apparently they agreed.

    Interesting comment - I would like to see any shred of evidence about the hp rating being less. Lots talk about it but it is hearsay - no evidence just a bit more internet canon. Ive seen CARB tests on Zukes and they put out the hp @ stated rpm

    Hey mate that 4 blade solas 13x19 seems to give you the best cruising speed, how accurate is your info? I'm looking at getting one of those for my next prop.

    Cheers

    Re: Suzi 140 07 owners

    Luke G,

    All the info is measured on GPS speed, same location, so is pretty accurate for my boat (trimmed before measuring). Not only was it up there for cruise speed still a fair bit down on the Yam but the fuel consumption (Lowrance fuel sender unit installed, only displays in gallons).

    So the fuel consumption for the 4 blade @ 4000rpm is 4.5 Gallons p/H, At 4200rpm the fuel consumption jumps to 5 gallons an hour. The Yam @ 4000 was 7.4 Gallons per Hour and at 4200 rpm 7.8 Gallons an Hour.

    The fuel consumption while testing has also been measured with all the 3 blade 19's around the same figures. The 21s have been in the 5-5.5 @ 4000 and up to 6.3 gallons per Hour range @ 4500rpm.

    1 gallon = 3.78 litres.

    Regards
    Honda.

    Thanks for that mate.

    At he end of the day the dealer who re powered it should have water tested and fixed it before you pick it up that is what we pay them big bucks for.

    Re: Suzi 140 07 owners

    Doing a bit more digging it appears that the gearbox ratio change has made no difference at all.

    http://www.romseysac.com/equipment/b...gine/df140.pdf

    Does anyone know when they change the box ration to 2:59:1?

    The sept 2006 models had the revised gear ratio

    I have given up on the 21 pitch props, More that 5 seconds to get on the plane, is plain dangerous, I have to cross a bar everywhere within a 100kms of where I live in Brisbane so that was an easy decision. I also found the fuel consumption for the 21ís to be excessive compared to the 19ís, still trying to get hold of a Mercury 20 to test.

    At the ramp the other week, I pulled up behind a bloke with a Suzi 140 on the back of a freedom sport 6m offshore, jumped out and had a chat to him, was interesting to see that he had the 13*19 solas 4 blade on the boat as well, he was getting the same speed in the rev range as I was, even the same top speed.

    Re: Suzi 140 07 owners

    Interesting figures, the 4 blade sure shows it's form when uncupped almost no-one runs a 4 blade well on a mono, I keep saying here cup on our rigs is like throwing money overboard every hour on the hour.

    You can do much better but you will need to think outside the square, I know it's more typical to just pick a bad prop from a crop of bad props and hope for the best, suzuiki did no favours when they changed leg ratio.

    IMO when you are ready for an end point, find yourself a 3bl true 20P even a 21P possibly? (aluminium even will do better than those above) decup it, then tip it until your max rpm is reached and be happy with the new found performance and fuel savings.

    cheers fnq

    Mate you seem to be having really bad luck with your setup

    My setup is very similar to yours, boat weights about 700-800kg + engine and equip, we usually have 2-3 people on board and with the standard alloy prop, without the bimini targa we hit 50-55mph, and with the targa and clears on we hit 45-50mph both at 6000rpm.

    Have recently baught at new ss prop and will be testing it over the long week end, should be interesting to see the difference.
