FINALLY .... repower...
 

I know this has been beaten to death.... Have a hook on a 09 115 etec that is a dealer floor demo i can pickup with rigging for 7000... this motor has 0 hours and will come with the 3 year warranty but not eligible for the extended ... concerns are the weight as i am replacing the 115 tower of power... I know there is a difference but i think the pump and motor cant be that much in total difference... the pump for the mariner is in the stern ..... also will need suggestions on propping.... i would think a 4 blade would be best on my MA but whatever does the best for pushing the sled with lots of A$$ on it.... currently the 83 115 cruise is around 19 kts.... tops out around 32 kts...
Thanks for the help as i know it will be actual knowledge...

PS..... what do i need to do about the fuel in the tank ???? I can burn most of it out before the swap.... but it will have some remaining. I also only use marine fuel... so no issues with that..

Rusty,
Unless your willing to drop down to a 90 hp etec or Suzuki for the weight savings, I'd jump on that etec 115 and still save a grand or 2. For the money with 3 year warranty, tough to beat. only 30 lbs more than the zuke 90 and probably 75 more than yours (move a couple of things around and your golden). The only other 115 I'd look at is the recent Merc 4-s command thrust variant...360 lbs with ample displacement and and a winning smile.

Send me a pm about that etec if you decide against it...:cool:

cheers,
Gillie

Sounds like a good deal Rusty! However I would try to get the dealer to throw a new water pump impeller in it as part of the deal, since it's been sitting for ~6 years without turning, so the rubber has probably taken a set. Otherwise it might be susceptible to an impeller arm breaking off at pretty low hours!

Whatever prop you pick for that motor, the optimum RPM for it is 5600-5700, so make sure you're in that range with the load you normally carry. (I prefer being at the top of the range or a bit over, as margin in the event you occasionally happen to carry a heavier than normal load.) BTW, check out that E-TEC owners forum . . . it's much like CSC, with tons of useful info from some very savvy tech's! Those V-4's love to rev so better to be above that range than below it. Also make sure you use an accurate digital tach like I-Command that ties in to engine computer, not some analog tach, as they are notoriously inaccurate! Before you start fooling with props, make sure the motor height is correct, with the AV plate on top of solid water, clearly visible when up on plane with motor trimmed out as far as possible. Most dealers mount them too low, causing extra drag and loss of top speed. I'd start out with a 3B prop for best efficiency, probably a 15" pitch for heavy load, but if your min planing speed is too high (all the Moesly designed hulls will plane at about 12 mph with the motors they were designed for, i.e. about 300 lbs or less for the 20). If min planing speed is too high, you can try a 4B prop which will add more stern lift and/or a fin on the AV plate.

I'd also run nothing but the XD-100 full synthetic oil; the engine computer comes set for TCW-3 oil, but the dealer can set it to run XD-100 only, where it will use less oil and burn so clean that you'll never have to worry about doing a decarb on it! My local dealer sells it in bulk for about $35/gal, if you bring your own jug. It's expensive but you won't use much on a rig that can get 5 mpg!

Thanks guys... pulled the trigger today. . $ 7306 wirewrite harness and binacle included... but no cables or prop.. so I have to buy a prop and either pay for installation or install it and pay for a dealer inspection and computer set up for the warranty...

I did look at the mercury... but the etec was such a good deal...

Depending on the gearcase ratio, a Solas Amita 4 blade in 17" or 15" pitch should work well. I have both. $100 each. My Yamaha F100 prefers the 15, but I bet the meatier Etec would prefer the 17.

Nice engine!

gratz on the motor purchase, E-TEC and Seacraft got together like peas and carrots! post pics once its installed!

ETEC Throttle Cable
 

Rusty-
You may want to research the ETECowners website & check with Bushwacker about throttle cables if yours is a mechanical throttle. I like my ETEC 150 HO on my '76 Seafari 20', but had a throttle sensitivity issue especially wakeboarding about 18mph. There are some discussions about this on ETECowners; make sure you have BRP cables & it sounds like there is a better grade of BRP cable with less sloppiness. Check it out & congrats. Look for ETECowner posts by Huey, Seahorse & Olypopper.

Cool Thanks to ALL !!!
FishStretcher PM inbound !!
Capt Terry I plan to use the Teleflex Ultraflex... they work really good in tight turns and are super smooth !!! I have merc stuff ill be pulling off for another boat in the yard ....

Lucky dog! Congrats! Get off yonder mountain for the sea is calling:cool:

Gilli...
The wife is headed back to the coast on march 25th !! so no running back and forth for a while after that.... I hope to get it mounted and the PDI check done on my next trip home for a few days ... but we added a new crew member to the family in the form of a granddaughter.... she had her 2 week check up today and her and The daughter are doing good !!! Since I cant go anywhere with out showing her off ... here are some pictures ... the last is 5 generation gap... my grandparents with my granddaughter....

Sweet pictures Rusty!! Is this the same daughter I met a few years ago in the Keys?? Congrats to you and Tab!! :)

Pretty sure it was .. I think yall met the baby .. ( blondie ).. And thank you she is already SPOILED !!!

Oops I was unclear.


Sorry, I meant they are $100 new. And it was a suggestion for one to use. I got mine at boats.net but I don't recommend them as a retailer- slow to ship.

But actually a bit under $100 there. If I asked $100 used that would be taking advantage of you!

Plus, I don't think my Yamaha splined ones would fit your etec?

ETEC throttle cable
 

Rusty-
One other thing to think through on the throttle cable hookup is my 2012 ETEC 150 HO, to accelerate the cable pushes on the engine throttle lever. I think all Mercs are like my 1985 Merc 150 where the cable pulls on the engine throttle lever. I discovered this when I adapted a PerfectPass speed control to fit on the ETEC. It was more difficult than on a Merc because PerfectPass is based on pull on the engine throttle like for the automobile-style throttle linkage on inboard watersport boats. Good luck with your new ETEC- quiet, quick starting, and fuel thrifty!

Terry
very cool !! thank you !! it will come with a binnacle... I just have to purchase cables... I can get OMC.. but because I am not getting them with the motor I am going to use the super slick Teleflex for tight radius ... I used tem when I replaced my mercury cables and they are AMAZINGLY smooth compared to OEM / standard merc....
FishStretcher
are they Stainless... I looked for them on boats.net... no joy.... hit ebay and damn the prices are higher than I remember !! But I haven't bought a prop in a while...
If yours is SS I think they actually may work and if you would like to part with the 17 I am VERY interested !!

Rusty, congrats Gramps! 5 gen gap is awesome. Lot of greats and grands is good! The joy on the faces of the great greats is priceless!

LOL... the GG never smiles and if you look close he really looks like Walter ( jeff dunhams puppet ) !!

and Im SUPER stoked on the JohnyRude !!! Emailed back and forth with propgods ( Ken ) and he recommended the mercury enertia 3b 17.... should se mid to upper 30knt topend range ... that will raise my cruise to mid 20's !! But he also said since I carry heavy loads I might wan to drop to a 16"... which is what I currently run on my OLD mariner.. so im am torn between the 16 and 17..... I was stuck on the 4b but after the recommendation from Ken and Denny ... looks like a 3b...

A 4B might not be a bad idea if you eventually plan to install a bracket! (Check the e-mail I just sent you!) Denny
