It looks like a 125 Hp
These motors were built for the American market and Were put on fletches Lovely engine when they're running right But very heavy 125 hp

115 is correct my mistake
And now it is not a force engine is made by Mercury Like I say it was made for the American market not the UK And so was the 125 Which is the same engine You don't see too many in the UK there're good engine

Funny you should mention Fletcher's as it came off one, the engine runs well (but has been sat idle for little while now, but has been kept in good order!)
It's a Mercury 115hp... it will be going on the back of my Sharp 19 running a 20 inch pitch lazer 2 prop ( I do have a 21 inch high five too)
should be fun! and quick....

Just did some work on a pals 125, is yours the 2l in-line 4 with the 2+2 config? Looks pretty similar

Umm...it's an in-line 4 cylinder do you mean 2 litre?
was just curious on the sort of speed it would be capable of on a Sharp 19 fitted with a lazerII 20" pitch prop,
started perfectly after checking it over aswell!
cheers

Yep, 2 litre. Does yours run on 2 cylinders at idle and brings on the 3rd and 4th about 2,500? The reason I ask is the 125 works this way and didn't start from cold easily or idle too nicely. Seemingly this is a trait of the 2+2. We went with NGK Iridiums and made a huge difference with this motor. Also installed a set back bracket and raised the motor to 3" below pad, the Laser II likes lots of water and didn't perform well with the lift. Ended up going with a Stiletto Advantage 23" and she turns it at 5,200rpm. I had to do a bit of looking to find a 3 blade cupped prop in the 4.25 gearcase

I'm guessing it does run 2+2 as idles rough but started easily from cold? I don't know any of the RPM's as hadn't hooked the tac gauge up at that point, engine is not lifted just mounted via the normal way but the skeg and prop are in good position

I'ld be interested to see how you get on once you have her in. We more or less replaced all we could on the 125, mounts, steering pivot bushes the works but the Iridiums were well worth it BR8-HIX, it's like a new engine. If you do go for them you'll need to re-gap the plugs to 1mm as standard gap is0.8mm. The 125 is on a Skeeter 550s which is a 18' cuddy and has to weigh a lot more than the Sharpe. Were getting 53mph with the Stiletto and got 46mph/5250rpm with the Laser II. Wot range for these motors is 4750-5250rpm and I was told not to run them hard on the limiter, something to do with the crank not being balanced

"more to be done", lol, famous last words! But I certainly can't talk as I can't seem to leave my Ring alone . 60 mph is great fella, you'll be giving a few lads a surprise with her. Pals 46mph was with 20" Laser II as well so yep more in her alright

to be fair it is spartan in side so very light!... and yeah never seem to leave them alone always have to tinker lol, (fitting a foot throttle next couple days)
not counting the speed as spot on due to been a hand-held GPS device but still very fast! and out stripped a Phantom 16 with a mercury 1998 90hp left him standing haha he wants re-match
all i want now is a bigger tank :/

Ah now, first time out and you've cracked 60 and laid waste to a Phantom! Sure you couldn't ask for more! As Sim1cat said they're a good old motor, certainly making all their ponies when in good nick. She's a nice looking package from your pic. Here's 1 of the 125, we gave her a lick of black and new decals when apart for mounts etc, not that I'ld want to be giving you ideas! Lol let the tinkering commence and keep posting, I'ld be curious to see where you end up

oooh that's a beast!
wasn't what I expected to happen if I'm honest!
The guy who sold me the engine did look after it nicely, the next thing I'm looking into is hydraulic steering set up (not happy with cable) any help on that would be good?
most likely end up skint but smiling haha

Skint but smiling, sure I'ld imagine all on this site can relate with that! Now onto the weird topic of steering. This is a weird one as I'ld imagine most people will have their own preference. The normal answer would be the one of the Telefex systems, now and this is a personal thing but I run a warmed up Yam 200 and get a good dose of chine walk at 70mph and I use dual cable rack and pinion as I find it easier to control the walk. If your not experiencing chine walk yet, you won't be far off and if I were to generalise I'ld say nearly most deep v hulls will experience this about 65mph+. Either way it's defo an aspect of your set up you need to look at running the speed your running. There are lots of pros and cons to all systems and it really comes down to a personal choice of what you feel to be best. I'ld suggest doing your research on all systems, lots of info out there and big differences in price too. So there you go, after reading what I've wrote I've been no help at all! No easy answer I'm afraid but homework is the key before you spring the funds
