BassMan11 Posted November 16, 2014 Author Report Posted November 16, 2014 (edited) Hey Guys, Just to give an update, I went and looked at the motor this morning and decided to pull the trigger. I don't think its a quite year 2000 because of the writing on the coiling but never the less it runs awesome. Its going to be a long winter. Edited November 16, 2014 by BassMan11
DRIFTER_016 Posted November 16, 2014 Report Posted November 16, 2014 Go in to your local dealer with the serial # and they will tell you the year.
BassMan11 Posted June 22, 2015 Author Report Posted June 22, 2015 Gentlemen, Finally getting out with the new rig I noticed right away the motor has not been running right. Fully loaded with 2 people the boat weighs 1000lbs and I am only getting about 15mph at full throttle. This can't be right can it? I have already brought it in to get a full tune up and all 3 carbs cleaned. Also I have changed the prop from a 10 pitch to a 9 pitch to see if this would increase the RPM's but it still sounds bogged down. Anyone have any idea's of what else I should be looking at? Any information or advice would be much appreciated. Thank you.
Raf Posted June 22, 2015 Report Posted June 22, 2015 you should be seeing upper 20 mph, maybe crack 30 in that rig. i don't have any advice to offer you though, good luck.
glen Posted June 22, 2015 Report Posted June 22, 2015 Tune up or down. Check carb linkage at all three carbs to make sure they are opening all the way. Or maybe it's only running on two
Sinker Posted June 22, 2015 Report Posted June 22, 2015 Does it have power trim? Where is the pin set for the trim? Maybe bring it up a notch and try again..... S.
Fisherman Posted June 22, 2015 Report Posted June 22, 2015 My 25 Honda was on a 16' Princecraft and with 2 people I could get 37-38kmh or about 25MPH.
BassMan11 Posted June 22, 2015 Author Report Posted June 22, 2015 It is a manual trim and I have tried all of them and it doesn't make a difference. The Boat is a 14' Sylvan and I would think at least 25mph would be my target speed. Glen, The carbs are opening all the way but I would agree that it does sound like shes not firing on all cylinders but I thought maybe that is how a 4 stroke sounds (my first one)?. Either that or a fuel delivery issue would be my guess.
MrSimon Posted June 22, 2015 Report Posted June 22, 2015 Are you saying that you already had it professionally tuned up and had the carbs cleaned? If so, then I'd assume it's running properly on all three cylinders and your problem is most likely motor positioning ...mounting location or trim settings - as was already mentioned. Any chance you have a long shaft motor on a short transom ... it kind of looks like that could be the case from the photos.

Any chance you have a long shaft motor on a short transom ... it kind of looks like that could be the case from the photos. That is correct. The mechanic is actually a friend of mine that works at a place here in Ottawa. He has looked at it again and thought it was a prop issue (which I replaced) but it didn't fix it. The motor is defiantly a short shaft and I have the cav plate at the proper location after doing some research.
Sinker Posted June 22, 2015 Report Posted June 22, 2015 It is a manual trim and I have tried all of them and it doesn't make a difference. It should make a big difference if you adjust the trim pin......something is up. Are you sure its the right prop? S.
Fisherman Posted June 22, 2015 Report Posted June 22, 2015 Going by the pictures, the pin that goes in the trim holes should most likely be in the center one, I guessing your bow may be plowing and not getting up high enough. It's unfortunate you're are fair distance away otherwise I'd give you a set a fins I had on mine. It made the world of difference getting up on plane and flying.
BassMan11 Posted June 22, 2015 Author Report Posted June 22, 2015 It should make a big difference if you adjust the trim pin......something is up. Are you sure its the right prop? S. I have tried 2 different size props (9 and 10) and the motor sounds the exact same..... this is going by a prop chart. Going by the pictures, the pin that goes in the trim holes should most likely be in the center one, I guessing your bow may be plowing and not getting up high enough. It's unfortunate you're are fair distance away otherwise I'd give you a set a fins I had on mine. It made the world of difference getting up on plane and flying. Correct I am in the centre hole. Front end is up and I am about 3/4 on plane. It just feels I am missing that last gear at wot.
glen Posted June 22, 2015 Report Posted June 22, 2015 (edited) Get all the prop measurements. Like 9 x 10 dia A 9" aluminium with your rig may be too small. Edited June 22, 2015 by glen
porkpie Posted June 22, 2015 Report Posted June 22, 2015 Have your buddy do a compression test if he hasn't already done one.
BillM Posted June 22, 2015 Report Posted June 22, 2015 Sounds like a fueling issue. Is the gas new? Fuel filter clogged?
Fisherman Posted June 22, 2015 Report Posted June 22, 2015 (edited) Get all the prop measurements. Like 9 x 10 dia A 9" aluminium with your rig may be too small. He has the right prop, same as what was on mine. Like someone else mentioned you may be only running on 2 cylinders. Friend of mine has a Princecraft 14.5 Fisherman similar to yours with a 30 Honda, that thing goes trans warp. Just for chits & giggles, while you're tied up at the dock and in neutral running, pull each one of the spark plug wires off one at a time and see if you notice any difference. Edited June 22, 2015 by Fisherman
BassMan11 Posted June 22, 2015 Author Report Posted June 22, 2015 Pulled each plug and the motor would run rougher. Not a carb issue. It must be fuel. Is your fuel filter supposed to be full of fuel at idle? Mine looks almost empty until I squeeze the pump on the hose.
Fisherman Posted June 23, 2015 Report Posted June 23, 2015 No it doesn't have to be full, mine never was at any time, it sort of lay there at a 45 degree and always had a small air pocket. I don't suppose you have the specs to check the timing? There's marks on the flywheel and cam that have to line up,
ecmilley Posted June 23, 2015 Report Posted June 23, 2015 is the fueline primer bulb stayin hard, try squezzing it while at wot to see if it trys to take off, or try different tank and line seen this problem many times with ethanol degraded lines sucking air and not leaking fuel
BassMan11 Posted June 23, 2015 Author Report Posted June 23, 2015 That is something my mechanic said he would check. It looks like a new belt so maybe the timing is off? Wouldn't the motor idle rough though if the timing was off?
ecmilley Posted June 23, 2015 Report Posted June 23, 2015 yes if the timing belt was off a tooth it would idle rough, if compression was good timing is most likey good, belt out will give a low steady compression reading usually and a low and steady vacuum ready while running
MrSimon Posted June 23, 2015 Report Posted June 23, 2015 Make sure your mechanic takes it for a water test. Sometimes it's hard to diagnose a cylinder not firing in the shop. I had an issue with the same motor where the fuel connector at the motor was letting some air in ... causing it to stall out sometimes. I'd double check all your connections.
BassMan11 Posted June 23, 2015 Author Report Posted June 23, 2015 Going to do a compression test tonight to rule out that problem (hopefully). Any guess on what the readings should be? If the compression checks out then it must be a fuel delivery issue. Agreed you can't really fully test the motor unless it is ran out on the lake. You can only do so much in a tank at a shop.
porkpie Posted June 23, 2015 Report Posted June 23, 2015 My 50hp calls for almost 200psi factory new, but it is electric start, I believe the electric start honda 30 would be somewhere close to 200 as well. Don't know about a manual start, might call a honda dealer, or try iboats.
