Guest stephanb79 Posted December 30, 2016 Share Posted December 30, 2016 Hi guys i just got the my new boat and I have taken it out twice and I have noticed the spray on the back of the engine doesn't look right and doesn't matter what speed or what trim it still does it any idea what it is or is it normal??

Fab1 Posted December 30, 2016 Share Posted December 30, 2016 (edited) Photo of the transom would help if possible. Any transducer/s,Bait tank pickups,ladders etc back there? hopefully the engine height on the transom is correct also.

rickmarlin62 Posted December 30, 2016 Share Posted December 30, 2016 lower your engine to running height and lay a level or straight edge from under the bottom of hull to your engine..me thinks your cav plate is slighty lower or dead level with your hull if lower you can raise...the water leaves the hull and rises slightly as it flows back towards your motor..engines on pods have a large prob with this as they need to raise their motor higher than normal..check your height then let us know Link to comment Share on other sites More sharing options...
rickmarlin62 Posted December 30, 2016 Share Posted December 30, 2016 engines normaly need to be raised 25mm for every 30cm back from normal i notice yours is half pod so your cav plate should be 25/30 mm above hull level Link to comment Share on other sites More sharing options...

I don't want to really move the engine my self but the dealer is in Melbourne and I'm in Sydney .. Link to comment Share on other sites More sharing options...
rickmarlin62 Posted December 31, 2016 Share Posted December 31, 2016 lower the motor so the cav plate is levl with hull Link to comment Share on other sites More sharing options...
antonywardle Posted December 31, 2016 Share Posted December 31, 2016 I think rick is saying that you should put your engine down as though you were out in the water then use a straight edge from the bottom of the hull to see where the cavitation plate is on the engine. From there, he will be able to advise you on the next course of action. He is suggesting that if they are at the same level then the engine should be raised. That's the bit where you undo the bolts and lift it up. Of course, I could have misread all of this ;-) Link to comment Share on other sites More sharing options...

Raymondo Posted January 1, 2017 Share Posted January 1, 2017 Other than some engine height tuning, how's the Mclay going Stephan? Link to comment Share on other sites More sharing options...
Trailcraft43 Posted January 1, 2017 Share Posted January 1, 2017 Lower your motor to full down. And run a string line from halfway along the bottom of the hull. Tape it on with gaffa tape. Then lower or raise the string line till it touches the full lenth of the hull and see where it is in conjunction to the motor cav plate. A lot easier than trying to use a straight edge on a pod type motor fit. Link to comment Share on other sites More sharing options...
rickmarlin62 Posted January 1, 2017 Share Posted January 1, 2017 could be a bit difficult if you have rollers like 95 percent of boats have..you only need two inches of hull with st/edge or level....Stephan lower or raise motor till cav plate on motor sits parallel with said st/edge..measure height above or below if badly wrong...then a resolution to your problem can be sorted..rick Link to comment Share on other sites More sharing options...

Hey mate so far I'm really impressed with this mclay the finish is great and handling has been good but I think I need to raise the engine one hole up and I think it will go a lot better it just doesn't feel right Link to comment Share on other sites More sharing options...
JonD Posted January 1, 2017 Share Posted January 1, 2017 (edited) I don't think I've ever bought a boat that hasn't been improved by raising the engine and fiddling with different props. Most manufacturers set them up a little lower I believe to account for new boat owners who don't understand trim that well. For tight turns a higher mounted engine needs to be trimmed in in order not to cause air to mix with the prop loosing grip (cavitate) but with a lower mounted engine you can normally hard turn without having to think much about the engine, this is why they mount them low. If the engine is to low this will cause more drag as well as excessive spray from the antiventalation plate. Check out this link which explains engine heights, you will note there's not really a right or wrong, it's more about performance. http://www.boats.com/how-to/the-outboard-expert-boost-speed-with-outboard-engine-height-adjustments/ If you think it may be low raising them even on your own can be quite easy but we can look at that next if you think it needs raising. By the way on my last Haines signature I raised my engine so the plate was 45mm above the bottom of my hull and my current boat is about 30mm above. jon Edited January 1, 2017 by JonD Link to comment Share on other sites More sharing options...
Guest stephanb79 Posted January 10, 2017 Share Posted January 10, 2017 (edited) Hi jond this is a good read thanks for the info but I think is matters aswell how far back the engine sits aswell ?? Well I took it to a marine shop in Forster and they took the engine up 2 holes and wow what a difference it has made I can get on the plan easier and doesn't feel like it's dragging now much better !! Thanks for all the info you guys gave me on this aswell really appreciate it Edited January 10, 2017 by mrsswordfisherman pm for name of marine business Link to comment Share on other sites More sharing options...
