2520 with Twin 115 yamaha GOOD/BAD?

[barrie]

looking at buying a 2520 with twin 115 Yams. We DONT run long distance off- shore to fish, mostly troll close to the beach. WHATTA think, not enough "giddy-up" for a long run if we choose to OR should i go back to a single 4-stroke225 with a kicker like on my old boat?

Send a PM to member Porkchunker.
He has a pair of F115's on his 2510 MVWA

I would think it would be really close to under powered, I wish I had twin 200's on my 2520XL, I have twin 150's , but if when I repower, hopefully no time soon, I will get 200, my boat fully loaded with gas , bait etc,etc the 150's are good , but 200 would be better, that only what I think .

Thanks for the info, that's what I was thinking also . I just sold a GW 27 Islander with single 250 HPDI and that was underpowered SO now i'm ready for a REAL boat!

Got your PM and answered you.

On the XL hull, twin F-115 would be underpowered. Twin F-150s would be OK. Obviously tara11 has some first hand experience with an XL and twin F-150s. He would be a valuable source of info.

I'm not a speed demon, so I don't mind going slower, burning less fuel. Twin F-115s are plenty for me on the MV hull. I would assume that twin F-150s would be plenty for me on the XL hull. But each person has his own definition of "sufficient."

i worked on a 28 maycraft cc with twin 115s. that boat was very underpowered, and the one time we had to limp in on one, it was really hairy coming through the inlet. theres no way the 2520 xl weighs less than the maycraft, i would not recommend that power for that boat.

I have been operating a 2520 with 115s on an extension for three years. I get good fuel economy, a cruising speed of around 22 knots. I max out in good conditions at about 30 knots.
I am consistantly carrying a passenger load of four to eight adults, crew included.
I spend a lot of time in the 12 to 15 knot range. I am perfectly satisfied with the 115s. I hit the starter and they crank. that is also very important.
It depends on the expectations of the owner I guess. You wanna blow out to a fish drop at 45 knots, fuel consumption be damned, then you should go to bigger engines. There is no end to the distance you can go once you start in that direction when you think about the thirty foot center consoles with four 300s lined up across the back..
Parker equipts their 2520s with the 115s. they know what they are doing.

 

[Porkchunker]

They equipped their old 25 MV hull with twin F-115s, but I wonder what they do with the new 25 XL hull. Methinks they go no lower than twin F-150s. Will check on their site later.

Yep...just as I thought...minimum of twin F-150

I have a 2520 DVSC with twin 150's. runs very strong fully loaded. Most of the time we cruise around at 22 to 28. the boat will top out at 48. Its nice to have the out of the hole power and the ability to haul ass if you want. With 115's I gather it would be ok at best, but feel 150's are the minimum for a 25.

 

[outofcommission]

What kind of cruising speeds could you expect from a 2530 with 150 4strokes?? 3 blades 4 blades

 

[CaptainJim]

the real question is what hull is it?

if its the DV then its underpowered...

i would think twin 115s on a 14 or 16deg MV would be acceptable.

my 14deg MV with a 200 is bordering on underpowered but I still have plenty of giddyup when i want it....

my cruise at 4000 is about 24-25kts, and WOT im humming at 32-34kts at 5200rpm

Twin 115s on my boat would be about the same speeds I'd assume but would be a LOT nicer around the dock in the wind. I've often thought of repowering with twin F115s but it's nearly as reliable and way cheaper to run one big 4S than 2 little ones

CP member Porkchunker has a pair of 115's on his 2510.

 

[Porkchunker]

Twins will give you more prop area and less slippage.

I actually do quite well in rough seas keeping on plane at low speeds.

Most of the time in the Ches Bay, I can't run the twin F-115s any more than 4,000 rpm because of the chop. Even if I had twin F-150s, I probably couldn't use the extra power 75% of the time.

I have a parker DV 2520 with twin 03 115 . I think they are great ..Its not speed demon but I cr around 4400 rpms 28 mph and wot around 35 to 38 mph.. They are great on gas and very dependable motors. We run 40 to 60 miles off and troll all day on 45 to 60 gals depending if we return in the dark

 

[cfarmd]

what about running the 2520 XL with a single F300 and a 9.9 kicker for trolling and back up?

2 F150s= ~1000lb
1 F300= 560lb

seems like that 300 would stroll and should offer some excellent fuel economy

I've added parker to my short list and I'm starting to look at them real hard, I appreciate any real world advice from actual owners, thanks guys

On handling characteristics of a 2520 around the dock with duel engines. It has been my experience that the props are to close together to make a lot of difference. That is the case on my boat. Also manuvering astern with a 2520DL, older hull design, is something to avoid.

Tip your motor up a bit so the thrust goes under the hull instead of against the transom.
It doesn't take much 'tip', but it makes backing a whole lot easier. :wink:

I have twin F200's and have found none of this. I am confident I can put my boat almost anywhere and she backs like a dream with the twins, straight back because of the counter rotating props.

The key with docking any Parker Pilot house is paying attention to the wind in relation to where you want the bow to go or not go. The wind is going to grab the house and unless you use that to you advantage you are just pissing in the wind.

I have no problem maneuvering with twin F-115s. Raise them up a bit and one in reverse and one in forward will spin my 2510 inside her own length (neutral steer in armored vehicle parlance).

Have done many a stroll down "Ego Alley" in Annapolis and done a 180 turn on my own space.
