There is a check valve in them that doesnt allow the oil to bleed down form te system when its not running.

Added: Be sure to check all engine bolts.

I lost 3 yesterday and caused a nasty oil leak. Thankfully no damage done and back on the water.

does anyone have this same type of information except for a godevil

Picked up a few oil filters and found that Stens makes a replacement oil filter for B &S. Found this during my search using the Briggs part number. At least the filters are still made in the USA

Stens 120-485 replaces Briggs-492932S

On the new PD lower units, what is the new silver allen head screw about halfway up the lower unit? This wasn't on the old drives. Is this another place to add LU oil?


FYI - Don't forget to grease the fittings for the FPR under the velcro'd clutch cover. Also check all the bolts/screws on the hydraulic trim unit. There is a screw on the backside of the hydraulic motor that should be checked too.

Wilson....there's a grease fitting in that plug!

I had an old manual and was emailed a new one, so I got it figured out.

Thanks

To KCM;
Lost Three engine bolts yesterday on my 32 pd,got the same nasty oil leak, Did you replace the gasket?, or were you able to put new bolts in and call it good.

Wix oil filter is 57035 not 51348. Crossed it with the Briggs 492932S after seeing the 1348 was too small.

Will that K&N air filter (e-4665) work for the 36hp pro drive?

Because it looks a little smaller.

Whar is MAX rpm on the 35 HP Kohler ?

lost 5 bolts & most of the oil. lucky i was at the camp when i saw it, the eng sounded like it was going to jump off the boat. i look back at the bolts real often.

Really good info. My owners manual has info on the unit, but nothing on the actual engine.

will these spark plugs works for a 32pd. i didn't see the specifics on what engine to spark plug. thanks

just got first surface drive.1854-36hp prodrive. is it normal after only 5 hrs having to add oil ? also baffels giving out in muffler

I have been trying to read and find the appropriate procedure for breaking in a new Pro Drive. What I am trying to figure out is hard to push it for how long. The best I have found is shorter runs at less than full load for the first 5-10 hours. THere is a lot of room for interpretation on this, especially on a modded motor right out of the box.

Is there a target RPM, that is a standard comfortable range to use during the break in period? Say 3800 RPM's, max 4000 RPM's for the first 10 hours? Just curious as to what some of the guys that give a chit are doing. Thx in advance. I would imagine with the mods I am going to do, the top RPM range will be 4250 trimmed appropriately...

Very good thread- thanks- i have just ordered a new PD motor and this sort of info is very valuable and this concise list V Good.

Here's a rookie question... On a console steer PD or GTR will the motor kick up if
It hit something like a tiller handle will?

Yes, but I have no earthly idea why you decided to ask that on this thread.

How much play can you have on the down shaft of a pro-drive. I am sitting at 1/16-1/18 of an inch. Is this acceptable? Seems like it is taking a lot of grease.

The play is most likely in the clutch but you should be fine

What RPMs those engines you work on run. Ours are running between 4000 to over 5500 and more.

What is the time/money to do the routine maintenance (oil change/greasing/air filter)??

Depends on how many hours you put on it a year.

How much money/time each time you have to do maintenance?

20-25 bucks. Maybe. Idk I always have most of the stuff I need

He's talking about the case bolts on the powerhead.

Ive got a 27 hp prodrive, 15 hours. bought it used. It starts up but quickly dies right after. I cleaned the carb, got new plugs and changed the oil. any tips from there?
thanks
jeff
