Surfriding Advice on good surf motor please

I agree 10mm stroker motors have good longevity and produce that torque needed for quick throttle response which can add to your fun in the surf. I could get 1 hr 15 minutes ride time with 900R 10mm with 46's.
 
If I knew about that setup combo 5 engines ago..

I hear that. For this past season I went with a 781 with RRP pipe and total loss. My thought was that it would be more reliable than a big motor setup and give me the performance that I was looking for. I was very happy with the performance of the set up but had a season plagued with electrical problems, water intrusion, and the inevitable dead batteries. Next season I'm going with a big engine, charging system and a b-pipe.

I had my heart set on the 10mm Dasa after riding one but with what you are saying I may just go with the 8mm.
 
I love my dasa 850ss. I only ride surf and it's a few mile ride to the surf from our boat ramp. 850ss with oem 46s and I use less gas than my buddy's maniac big bore with 38s. And this 850 doesn't fail to send me to the moon

I have both packages.

My predator is a 10mil 1000 on DASA 48 carbs and 148 pump

My reaper is a ss 850 on stock 46's and a 145 pump

Both b pipe and stock electronics (enhancers and light flywheels)


My predator I can get about 1h15 min

Reaper is 1h30 but could go maybe 10 more min I just don't want to risk it

When I ride the predator then go to the reaper I'm always like man this engine just rips and I can't really tell the difference between the two.....until I then ride the predator again. The 10 mil just has so much more grunt than the SS it's crazy. Easiest way to describe it is the 850 is a 250f and the 1000 is a 450 dirt bike. Simplest way to compare. You really can rip off any trick combo in any condition since you can just floor it at the bottom of a small wave with hardley any run in and still get around and still throw a big combo. The 850 you need to have some run up to get up in the air

I rode my 10mill for 14 months. I ride all the time. Like all the time. We took it apart before surf slam and we only needed to change 1 piston if we really wanted too! We decided to just change them both anyway and that is the extent of my maintinece. Mind you, I never sunk this motor so that helped longevity as well but as far as having more maintenance on a big engine, that hasn't been the case

@Jet_jase chew on this bud.

I was for some time a 701 FTW kinda guy. I had my limited 701 and mag pump and I preached forever that it's enough. In my waves in Oside on a big day, sure it's enough, knee to waist high, nope. Super boring. No flips.

Mind you I don't use trim.

I set up my Euro boat for IFWA last year and I made it the same as my boat at home. 850 SS 46 145 mag pump.

Everyone that year mostly had 950 and 1000 even 1200 and I was like screw that noise I don't need to die. 850 is the best out there.

I went against pierre in the uk and it was a very weak and lazy wave. And shallow. Pierre had a 8mm 950 with a stock 144 pump and was going to the moon. He could wait until the wave was correct and launch UP into the air getting big amplitude.

My set up I had to get a run since mine doesn't have that low stroker grunt. So I'd come from far back almost WFO, time the curl, hit it, throw a Madonna or whatever big variation, and juuuuust under rotate and hit the ground.....

I was hitting the waves so hard I was exploding through the waves and going FAR in distance, not UP in height. I lost the round even though I had more technical tricks, I just couldn't match pierres amplitude.

That was the last time I ran an 850 and 145 in a competition ski. The U.K. Changed my perspective on what to run for contests.

My next ski is my current. 10mil 1000 148. It is the ultimate competition ski and fun factor ski. You can hit small or big waves, no trim, get around, go HIGH and force combos.

In the end, if you ride big waves, 701 will work. If you ride big waves and also medium waves, the 850 will work. If you ride big waves and also knee high waves and you have 6 min to throw down in any condition trying to win, the 1000 Destroys the 701 and 850. Best all around power, linear, and reliable.

In competition. More power is ALWAYS better than not enough power.

Ps, I feel like the skis handle better with more power. If your off balance and falling over, just pin it out of it. Re entries are so much easier. Rolls off anything. Flips off anything. Spins anything. Easier to surf ride having more bottom grunt. I will always run the 1000.
Definitely have to get used to it in big waves though and be careful with throttle control.

What else is a trip is I feel like the 850 in the reaper is the max amount of power I want in that hull. It's wider hull makes it flip faster than the predator so I think more would be scary.

Pss- that was really long. I hope it made sense.

Zack that's some write up mate, thanks for that.
Completely makes sense when you put it like that.
So, thinking it through I need a competition motor I can run without the worry of running short on fuel.
For where I ride I need a motor that will do 1hr 30 mins so sadly I'm never going to have anything like a 1000 cc .

No worries mate.

What about the 5 gallon in the front and the rear 2 gallon tank? That way you have 7 gallons and should be able to get 2.5 hours with a 1000?

That's my current thinking and a ride buddy is just about to go down that route. I have been offered a Dasa 900 10 mil so maybe that with 46's will be a good combo.
 
If you have a good pump and run oem 46s for carbs won't use much more gas than a limited 701 setup. Keep your props fresh and pull up on the beach the least you can. I use less gas in my 850 then guys I ride with with a 701/bpipe set up

You use less gas cause you're always up on the beach unsinking your ski

Good info here. Sounds like the stroker BB is the way to go. Fuel is a questionable asset.
Lightweight hull, light rider, skill level all play a role into the power to weight ratio.
 
Another rider in our group runs 1000 10 mil, 49carbs and lasts 45min per tank. My engine (48carbs) lasts 1h10min. Both engines have plenty of manageable power for the surf and instant response bottom to top.
I run bpipe, he runs PFP.
If I knew about that setup combo 5 engines ago..
If you're referring to Seth's titan, i think its an 1100? But yes 45 minutes is sad

I've recently been sponsored by Loki customs so i'll be going with his new motors, So i will be going for a bigger bore on my 61x 701 with a 5mm ADR stroker crank. Depending on bore i'll have roughly 800cc.
Then i'll be looking to upgrade to a 148 pump.

So, I thought i'd update this thread as i have just completed the 3 Euro rounds. I stuck with the 144 solas and rode the 61x +5mm.

The last 3 weeks where a big learning curve in terms of competition riding and the wave size was'nt really that great. Portugal threw up some good lumps on just one of the days and turned into a shore break when the tide was in. France was even worse with me getting knocked out in the 1/8 finals in small 1-2 foot surf (I needed a big motor).
The UK round was also small until we waited for the swell to come last monday we ran the comp from the 1/8 finals then. I managed to bag 4th place in the UK round due to some luck and there been good waves to send my small motor off.

I did the trip with Gomez and Abraham so managed a go on both their ski's. I really liked Marks 1000 Dasa with 155 pump, the power was noticibly there and i felt i could go big if i really held it open and the hook up was unreal comapred to mine.
Abrahams ski on the other hand is mental!! That guy is crazy riding that in surf but then again we know how he manages to go so high.

So as much i read back through this thread and i thought i did'nt need a big motor back then........I do NOW!!! Haha. Watch this space as i'll be getting some big CC's soon.

Also looking at a trip over to surf slam with my buddy here if i can manage to borrow a ski.
