Runing in a new engine

after picking up my new boat and my first day out i was told by the dealer
20 hours was the runing in time and during this period take it easy i asked
what rev limit i should keep to and was told 3000 revs and to keep varying
the power but you can go above that to get the boat on the plane the most rev i did at weekend was 4500 for a quick burst i will be out this weekend
but i cant believe that the book that comes with the engine as no runing in
section. am i right in what i am doing. the other comment is when the rib is
being towed it said in the book not to use the power tilt or pin use a engine prop
the dealer said use the pin ?? its going in to fix a fuel leak tomorrow a bit of a pain but it will be ready for the weekend

Now I'm worried - I was told that it was OK to trailer my outboard with it held up with the power trim....

I was always told never to tow on the power t/t.

You lift the engine up on the tilt and there should be a metal catch on both sides of the engine that hinges down and you lower the engine using the tilt agian untill it rests on that catch and not the hydraulics.

it says

IMPORTANT Do not rely on the power trim/tilt system or tilt support pin to maintain proper ground clearance for trailering. the outboard tilt support pin is not intended to support the out board for trailing

taken from operation and maintenance manual 2003 700 pages 27 in english

In that case it's a wooden wedge all the way! (Whats the point of the pin then??)

Two dealers have told me to tow with the engine up and the locking mechanism on...yes it says not to in the Suzuki book but with it down I would hate to go over a bump! This was discussed before and the general consensus was 'keep it up'.
I can't work out why they put a locking mechanism on but then tell you not to use it for towing?!
When my engine had its first service the computer attached to it told the dealer the revs that I had used and for how long! So yes stick to the running in period.

I had a near miss while towing a boat along the side of loch lomond, foreign bus on my side of the road so I opted for the ditch...

Anyway point is at least one side of the trailer and boat were airborn at some point, destroyed the rim that went in the ditch and damaged the bearings, also pulled the tyre off but otherwise ok, including engine which was sitting on the steel catch not the hydraulics.

I think the manufacturers are protecting themselves against any eventuality, did you hear about the American Winnebago owner who put it into cruise control then left the controls to make a cuppa? He sued the manufacturers successfully as the manual didn't say he couldn't.

Running in

Daniel,

In al my years of boating, i have never heard of a 20 hour run in, i have had many engines Yams and Mercs but only need 10 hours run in period. After 1 hour at half throtel you open up for so many minutes, check your manual it tells you what you should do, not what dealer says so.


Richard

I understood the rules to be: Don't tow on the Tilt Lock as the engine can swing upwards when bouncing and allow the tilt lock to release. Engine prop should be used or others say a piece of wood. Apparently the pin is to take the strain off of the hydraulics when stored and stationary. I've heard 100% against towing with just the power tilt and nothing else.
