dropping a new motor into the GSX

[faded]

Wellllll !!!!!!!!!!!!!!!!

Is it done?

i misplaced 1 of the 4 halved rubber mounts that goes on the exhaust cone. my local dealer only sends out orders once a week or so, so i'm waiting on them now. should be done this week, if they can get that bushing to me. :willy_nilly:

Wellllll............ I guess that happens.

 

[faded]

it may have already been missing. i always had problems with one of the bolts on the cone coming loose. the threads on my old block were stripped by the previous owner. the bolt would loosen and wiggle out and i would find all the parts in the hull. the first time i noticed was when i found the bolt under the motor one day.

the new block has proper threads so i should be all good now. the bushings were a little torn up so i don't feel bad changing then anyways.

i do have to slap the jet pump on still. maybe i'll do that today.

I just wanna say thanks to you guys, this post is almost the same process I am getting ready to endure with my gsx. Good advice dr Honda!

Thanks, and post up when you start doing work on it.

Will do.

i still haven't pushed the button. everything is bolted down except the jet pump. the weather changed here and it has been cold and wet. the rest of my work will take place outside so i have to wait for a few sunny days. i will keep you all posted.

I understand. I have 4 large projects that I put on the back burner because of the cold weather here. I know I want them for the spring thaw... but it's hard to get motivated when it's cold. (and dark early)

my "Clymer" seadoo shop manual. says it in the maintenance section and the rebuild section. "ON 787 and 947 engines, refill the counterbalance shaft housing with 30ml (1 oz) of SAE 30 engine oil ..."

The 1999 factory service manual also states SAE 30 on page 02-04-03.

 

[Rusty75459]

I thought I read somewhere that the SAE 30 was a typo...
I could be wrong.

 

[seadooya]

either way, and i'm sure it'll be debated, but that 1oz oil will only bleed back into the combustion chamber. I've read also, using 30wt oil, but common sense says, to use 2-stroke oil. However it is a good idea to check the oil, about every 40-50 hrs, or refill if need be.

I was wrong... From a closed thread

I did a little more research on the 30 wt. oil. 1oz. isn't much oil and it appears that it is only added when you rebuild the engine. you shouldn't just fill the oil up. It's purpose is to help lube the counter balance shaft after assembly. Also this oil wouldn't come out the exhaust...that would be from your 2 stroke oil in the injection system.

it's still raining. so much so that i haven't even been able to fish. every week that goes by they call for another 10 days of rain. the lakes are all full, so that part is good. but it hasn't dried out in weeks. maybe next week it will.

i filled the last motor to the top with 30w. i misread the fill level somewhere, so i simply topped it off. it ran fine for 15 - 20 hours. then one of the crankshaft bearings went. i have no idea why. i cracked the case in half and the only damage i saw was to the needle bearings. it even still turned by hand, with the toasted bearing.

i kinda feel bad dropping in the new motor then just having to walk away. it's under an awning, on gravel, with a cover so it's dry and safe. but she's cold, and lonely, and keeps calling for me to finish her. good thing i got the 2 year warranty.

Your projects sit around longer than mine. :biggrinjester:

it's rained 21 of the last 23 days. not just rain, but pouring rain. it was in the 80's back when i started all this. :-/

 

[faded]

the sun came out. :coolgleam:

she fired right up. :hurray:

the idle was a little high so i bumped it down to 1350 on the hose, in the driveway. i need to scrub her up real good and hit the water. tomorrow is a long awaited fishing day so i won't make it out then. we are heading into a nice warming spell though, and i have new wetsuit gear. i should be able to make it to the water within the next few days. i'll keep everyone posted.

i want to thank everyone for their help and support.

i'm not fully in the clear yet, but i am feeling a lot more confident. :biggrinjester:

COOL !!!!!

the idle was a little high so i bumped it down to 1350 on the hose, in the driveway.............

Ummmmmm..... It's not going to run once in the water. Without a load on the pump... your idle should be around 3000 rpm's. There is no good way to set the idle out of the water... but bump it up to 3000, put it in the water, and re-adjust it for 1500.... go for a ride, and let it warm up... then adjust it one more time until it's low, and stable. (normally around 1500)

Good luck, and let us know how the first ride goes.

 

[faded]

i kinda knew that about the idle speed on the hose, but changed it anyways. i have no idea why i turned it down so low, other then to hear how it sounded at low idle. i will make sure to bump it up before i go out.


i was putting on the carb cover when i dropped a washer. i wiggled my hand under the motor to find it and was greeted with a puddle of oil. while hooking up my oil lines i hooked up the IN line first. oil filled the block and started coming out the OUT side before i could stick the hose on it. oil flooded out for a brief second. i thought maybe this was left over from that so i mopped it all up. today there was another puddle under there. upon further inspection it appears it is leaking out of the fitting under the carb side. i removed the carbs and tighten the hose clamp on the hose and gave the fitting the slightest bit more of "torque". i have a clean paper towel under it now that i will check shortly to see if more oil appears.

these 2 fittings have scared me from the beginning. the are very fragile. i did not use any type of thread tape or sealant on them. not sure if i should have or not. at this point i'd be scared to try to remove them. let's keep our fingers crossed. i wash just gonna wash her and take her out tomorrow. hopefully i still can.

 

[Dr Honda]

I do the same thing when I put a new engine together. It always sounds way to high. I just wanted you to be aware that it's going to need to be re-adjusted once in the water.

Yep... the oil fittings are thin, and you don't want to over tighten them, or they will snap. I always put something on the threads. Either RTV, or fuel safe pipe sealant. (Used in Diesel fuel systems)

 

[faded]

i let it sit for 3 days and found a small puddle again. very small this time. the size of a quarter, as opposed to a couple tablespoons full. i gave the fitting another 1/4ish turn. i'll check again in a few days. i may take it out in the meantime. i don't think there is any pressure behind any of it. and as long as i don't run out of oil i should be fine. the lake is still in the 50's so i don't know how long i'll last. maybe just run it an hour or so. until my toes freeze. then come home and give it the full "once over".

 

[faded]

i'm still getting a little tiny bit of dripping. i'm pretty sure it's the fitting behind the exhaust now. it's very minimal and i'm not gonna tear everything down at this point to worry about it. i'm afraid of destroying all my fresh gaskets.

the weather has been warming up but the lake is still in the 50's. i may just tough it out in the next few days and go run it for an hour or two. i know, i keep saying that, but this time i mean it.

i added the full quart of break-in oil provided with my new motor. my fuel tank holds 16 gallons. i have my oil lines still connected as well. i scrubbed her down and put on a fresh coat of wax today. when i was done i hooked up the hose to adjust my idle. it fired up immediately. the only problem now is all the smoke. is this typical when loading it up with the extra oil? :ack: i assume so, but want to be sure. i would think a lot of smoke is better then no smoke at all.

 

[Dr Honda]

Sorry I missed this... but yes. A new engine, with extra oil in the fuel... you will have smoke. Once in the water, and warm... it will burn the oil more efficiently, and the smoke will be minimal at an idle.

BUT............. just to make sure you didn't pull a "Rampage".... check the cable going from the carb, to the oil pump. At this point, just make sure the arm on the pump is moving with the throttle. Since the arm is spring loaded, it is easy to get it flipped all the way around. If it got flipped, then it's going to smoke like crazy !!!

Once you get the idle set for real. (in the water, and not on a hose) you can adjust the cable on the pump.


Regardless....... smoke is good with a new 2-stoke engine. (bad with a 4-stroke)
