Engine Trouble

Ferm - Skools,
Can someone give me a quick rundown on what the process is for doing a powerhead swap? I am no master mechanic but I think I could handle it on my own, I am just not sure what I should expect to be doing. I understand that I will be bolting on all the electronics for the ignition and carbs but what else am I required to do? Once she is all put back together am I good to go or is there timing adjustments, carb tweaking, etc? I am still looking for a total replacement but I have found a rebuilt powerhead for 1900, and he doesn't need my block so I could sell that to get some cash back. Seems like a good deal to me.

At home I have this guys number who is moble and maybe you could contact him to see if he would be willing to help you with the job. He knows motors and is fair in his pricing. He worked on my motor for an hour plus and only charged me $75. Not sure if he is still doing moble work as I heard he got a job at some Marina but if you like I could get you his number.

Not sure i would got a 1900 motor?? I bet they were gas guzzlers!!
 
$1900 is the powerhead completely rebuilt with warranty. Not my favorite option but may be the cheapest at this point.

There is the obvious swapping of all accesories and bolt ons that includes flywheel, stator, pick-up, ignition, coils, harness, starter, plugs, intake, carbs, possiblt reed replacement, thermostats, hoses, fuel pump and so on and so on. Then there is the mounting bolts that can sometimes be a real PITA!!! or just come right out. Then you get to replace the water pump as well, and then go through and do the link and sync on the carbs and ignition, find true top dead center on the new engine and mark the pointer. After you get her started up then you can live through the smoke from the assembly oil burning off as well as paying EXTRA attention to if it's pumping water as well as how hot it will run for the first 30 minutes. After you get some break-in time on it you can reset the total timing and do a quick water test and rough in the idle. Get you a few hours on her and do the final adjustments as well as possibly do some re-jetting of the carbs if the engine you put back on was bored or ported at all.

It is one of them jobs than can go easily or painfully. Also don't forget to figure in AT LEAST $500 for OH SH!TS when doing the job. I have spent more money on OH SH!TS than the actual rebuild on some engines.
 
Thanks for dropping a turd in my punchbowl... You make it sound like a real headache. I know your right though, it is one of those projects that if all goes as planned its an hour job, if not break out the check book!

Luckily its only January so I have some time/options. I am still looking.

Thanks for the run down Ferm.

ferm is right i've had some go easy take 3 to 5 hours to swap and some go bad hard and b!tchy and take 3 days lol. plus the extra $ you always end up needed to fix the oops. if you haven't and are in any fear of something i'd say take it to someone to swap then you can fuss at them if it isn't right plus if you do something wrong i bet they will void the warranty.
 
Seen both of those. The brand new leftover would be sweet but I am sure he wants way too much for it. I am after a 99 150 with boat and trailer listed for $3900 pretty close to home. Will know more this weekend, he is sending me some pics and additional info.

-Svence
 
The 99 looks good and if all ck's out and a little dealing you have a nice motor

I hate fools that don't give you a starting big to get going. That 05 is going to be a good amount, and to start at a $1 is a pain in the a$$
 
Just saw that. 850 hrs...seems like a lot???

And I have to add some cash on top for new controls/cables/gauges.

-Svence
 
850 hrs aren't much on that motor, i'd take that Yamaha over a Johnson Evinrude in the same yrs any day. good buy if i have my Sea Ox completed i'd buy it and be riding since i already have all the yamaha controls. a new set of 704 with digital gauges yeah i'm looking for a yamaha for it, i'd just rather have a HPDI 2 Stroke Yamaha 150 cause of the wonder fuel mileage they get.
 
He said he had issues with ethanol jamming up the carbs, got them cleaned out and added a 10 micron filter to solve the problem. Besides the carbs is there anything else I should worry about?

-Svence
 
just do a leak down test and you should be good as long as she runs good go take a test ride before it's removed and then report back how that Parker rides lol
