soz silly question: outboard trim angle

arkamelis · 06 January 2012, 19:33

hi
can someone tell me, is a outboard suppose to be parallel to the transom 100% and at this point it would be classed has down.
what im getting at is, when using power tilt should the outboard come alittle way in towards the transom so it has gone beyond parallel

or should i just give up on boating altogether

i will be setting up my trim sender and gauge, new boy

If I understand your question correctly then it is possible to trim some/all outboards so they are trimmed in "more" than parallel to the transom. Depending on the angle of your transom etc - you may never need to use it that far in.

It is not a silly question - indeed it is a very important question as the trim of the engine has a very important influence on the handling of the boat.

The link below explains the basic theory of engine trim and rather than giving up boating I would encourage you to go on a RYA Powerboat course where you will learn a great deal and be able to ask all the questions you want to help you enjoy your boat alot more

hi again
just had a read through the link ribochet posted, and all is clear now, i understand now why my boat/outboard when i took it out for the first time sounded at times like it was well over reving but going nowhere" leg was out to far and taking in air" dont think i needed to get a trim sender and gauge set up now, but i think it would be good to see where the leg position is"peace of mind" .

Get in the habit of looking back to see what angle the motor is at (I usually tell by the slope of the top of the cowl.) In time, you'll be able to fairly accurately judge how far up or down the motor is at a glance.

Or, get a trim gauge.

With time you won't need a trim gauge or need to look back, you'll be able to trim the motor by how the boat handles.

Very true, helming after dark I find is an excellent way to learn how a boat behaves and to get a feel for her.

hi again
i have taken on board all of your useful info and tips, and cant wait to get out on the water to play around using the power trim, i have now installed the trim sender unit and just waiting for the dial to turn up so i can link it up, i think for just a visual idea for now, i will use the gauge to get use to the trim and some of the right positions that may be required, and after time i will just be able to feel its right location. just like to say thank to you all for your help

Yeah, I have a similar problem - no gauge. You can tell by the note of the engine as well - it will "sing" rather than "grunt".
