yes it was quite the build,, i would of like it too be a 100% restor but the floor and seats werent in bad shape so i did the transom added some braces and we'll see how she lasts,,,i was planning on resoring it again when the time comes but am already looking at seabolds stvs and hydrostreams i think one of those would be a better fit for my 225...i have an 85 i could put on the winder if i ever decide to sell or fall inlove with another boat but for now she's my girl ......winter is around the corner so i can tstart another boat project,,,i still have the baja to find a new home for.. |

nice boat! I would check and probably replace the primer bulb in the fuel line, make sure you use a oem 3/8" bulb, merc, omc, etc, check the line to see if its soft too, if so replace with a good ethanol resistant line too. checking the carbs on a used motor is a great idea. the origional pumps on the early yamaha's were not supposed to have stainless internal parts, apparantly this caused some problems with the pump gas available now, I replaced both the pumps on my excell just to be safe. I would also remove the inlet from the fuel cell and see if its clear and if it still has the anti siphon valve in place(1"spring and ball insite inlet fitting) if so tale a 1/4" punch and knock it out. make sure the inlet pipe is not pressed right against the bottom of the tank too. I know this is an expence, but the 25" mid will not work with that boat, you will need the propshaft at least 3" below the bottom of the hull or higher to get any high speed handling, dual cable steering with the slack adjusted out is also a must. if it were mine I would also install solid mounts.That is the most power I have seen on one of those! very cool.Also make sure you install a water pressure guage, eith but the yamaha kit, or if tour using an aftermarket guage , you need the yamaha adaptor.btw , these motors have a knock sensor that retards the timing, you need to run super fuel all the time, it won't hurt the motor, but it will run like sh*t on regular.

thanks for the reply ,,great advise ,,i am looking for a 20" mid section, but iv already spent all i can afford on her for now so im just trying to get her running good and learn about the motor for now,,,,i dont have a fuel cell, iv just been useing a plastic tank ,it has a new line and bulb,and it does seem a litle restrictive and has a hard time venting im sure that is a huge problem i will address before my next test,i also deleted the fuel hookup on the motor (it seemed restrictive), i had the carbs appart they are spotless,, iv been running 91 sunoco gas in it. and amsoil hp,,(iv heard about the knock sensor and experienced the regular gas retardation lol bala general store sold me regular and told me it was 91 octain with no ethonol but it was noting but regular 87 octain motor ran like crap i really thought i did damage but i threw some 91 in it and ran good again..). im looking for dual cables used or cheap or even free would be nice i'v replaced the impeller and the water pickup,,...im going to get a fuel pump rebild kit see if that helps...and will have to get a water pressure guage for it,, damn long list i have now.... i need too find some work |
