F70 Yamaha fitted

[scoota]

Running the 13 1/2 x 15-K standard prop Mike.. no foil and happy with that! Good trim and no porposing.
Hole height was critical and would like another half hole higher to be perfect..

Might see you on the water around Bribie and catch up one day Barra...

Scoota...

Guys, which fuel/water separator did they fit when installed ? Some sort of yamaha 10 micron or a racor or something else ?

[deckie]

Never mind about the filter, ended up ordering one of these donks yesterday with the small flush mount throttle rather than control box. $105 for a clear bowl Racor sounded pretty good, betcha they're about $80 for every cartridge replaced tho...damn things are a serial ripoff and was kinda hoping to get away from them.
Told to still avoid ethanol like the plague. Some things never change.

well im all booked in for the 10th Oct.....which i dont mind as i still have a bit of work to do on the tub, finish the floor, some leccy work, mount bilge pump, if time allows might get the upholstery redone.

[deckie]

Hi guys just got back from camping/fishing trip, wow what a motor goes like a bat out of hell.... top speed is 60ks @ 6200rpm in my boat, i am happy with that... i have a 60lt fuel tank and got some 140ks out of it and still have fuel left in the tank, may only be some 10-15 lts left there but i am happy with that as well. As would have never got any where close to that with the 2banger.
i found that the motor tucks way back in so you do need to trim it a little but other than that all good. Got almost 12 hrs on it now and still love it.. hit the key first thing in the morning and it is ready to go after i let it warm up first..
If weather is all good will be out this week in the bay for its first real trip, so looking forward to that,,,

Hi Scoota will have to catch up one day mate till then have a great one mate and enjoy..

[deckie]

Like the way they look too.
Very happy with the way this one went on. Still havent seen it running yet, and its going back next week waiting long weekend for different prop after water test spinning 5700 with standard prop but he wants 6000-6100 apparently.
Photo looks kind of wierd proportions to boat with camera angle but good view of the donk. Will hopefully turn the key on a quiet day late next week.

Good onya deckie you will love it mate.. the 6000-6200 you will up in the right rev range, i sit mine on about 5200-5500 when cruising and it is doing 50 odd ks.
Great on fuel as well you will notice it that is for sure, i went out the other weekand did some 82ks and used 35lts but that was in the swell for most of the trip os was just taken it easy around the 25ks mark so used a little more fuel with that.

Mine is almost ready to go back in for its first service 18hrs on the clock now..

when you first put it in the water you will hear the tell tail over the motor when at the ramp, just so strange to hear it if you know what i mean. Even when it is in its rev range you can still talk to your mate and hear each other without haven to shout..
I found the foil / fin on the back helped to get my boat up and out of the water faster and better, but i do have a 60lt fuel tank at the back as well, would love to put it under the floor but no room there i think... floor solid so i am not going to cut it to see if it will fit..

[barra71]

sorry for any spelling mistakes just had a opp on my shoulder and can only use one hand..

Hey Barra..re tested with a few props and the 13 1/2 X 15-K came out best now revving 6100...same as scoota's.
Finally turned the key on it today and cant even figure out these silly multifunction gauges which have only been around for about 200 years already...but hey noone said i was smart. Between those and the stupid sounder and gps and other crap i've got instruction books up the wazoo and just about over it already after 2 hrs. Might just keep the warranty book and turf the rest .
Great donk tho...this motor is the first chance a lot of older hulls have had to be reborn with a 4 stks as the weight as come down. Slid the thing off the trailer and had a glance and not an ounce of arse heaviness about it, plus surprising holeshot compared to the old 2 stk. Looks like wont need a permatrim coz it bounces up nicely and planed nice at low speed with nose up a bit. Massive great rooster tail from the trannie but holding bottom at 25 knts so will just put a shroud over it. This thing only carrying 50l fuel at the back plus a spare 25l taken out for trolling days and a 12l reserve kept up front. Batteries were moved fwd which seems to have helped performance slightly but will do some donuts and give it some sea next trip out and check how the weight distribution goes when its not so friendly.
Nice donks these. Wayno is putting one on next week by the sounds.

Soungs great Deckie, you will be like what the f with the fuel i did a run the other week 85ks in a good swell, that was from bribie to Smiths rock and back, so up and down on the revs a fair bit and only used 35lts and i only have a 60 lt tank. so i think you will only need your 50lt tank mate. On a good day you should get about 130-150 ks on that tank maybe more as my boat is not as light as a tinny.. Did you notice that when you are at the ramp that you can hear the tal tail hitting the water over the motor. They are just such a great motor i love it....

Wayno when you take your boat in to get the motor fitted let me know i will drop on down to Brisbane yamaha and catch up with ya on the day mate.

[wayno60]

yes mate at this stage everything is set to go thursday next week. Im coming up from the goldie so they are going to do it in one day for me. cant friggan wait.

Just on the props, both your boats, im thinking will be heavier than my tinnie so proped right i should get to the 6300 pretty easy ???
