16 ft Currituck motor height setting/E-TEC engine

Member Posts: 4 Comments: 0 Joined: 08/19/07	I have a 1966 Currituck 16 that I repowered with a 90 hp E-TEC. I am having problems with the bow porpoising. I have to keep the engine tucked down and can barley trim it out. Any suggestions? I am also having problems with the engine popping but not loosing power, the Evinrude rep says that the engine and boat don't match up and to just live with it. I don't believe him. I was wondering if anyone else has had the same problem. The engine only has 30 hrs and should not be popping. Thank you. Gary Edited by Tom W Clark on 06/27/08 - 9:07 PM

All the way down? 1 hole up? 2 holes up? If you are sure the engine height is correct, then another prop might help with the porpoising. Others here with the same hull and engine will hopefully let you know what works for them.

Second thing is to call Evinrude and regester your complaint with the motor and the dealer. The excuses the dealer gave you are nothing more than that. If this does not work let me know and you will have to move to plan B. Plan B has been succesful for me . keep us updated. BG

They are just now getting their reputation built back up after many years of a poor product. I agree that it is either a mounting setup problem or a mismatched prop, but no way can I buy that the boat and the motor are mismatched. Too many 17's out there with 90 ETECs on them. Once again it sounds like a dealer that doesn't have a clue what he is doing and is too busy or stupid to expand his knowledge, which is a shame. Keep us posed please Tom 1979 Sport 15'

When you say Evinrude rep, are you talking about your dealer? Mechanic? Customer service person on the phone? An Evinrude Regional Representative? What did they mean when they said the E-TEC 90 does not "match up" with a classic 16'/17' Whaler? That is most certainly not true as evidenced by the numerous successful installations of the E-TEC 90 on the 16'-7" Whalers. In fact it is one of the very best choices available today for a repower of that hull. Edited by Tom W Clark on 06/27/08 - 9:12 PM

I would like to know what other 16/17 owners are running on the same boat with an etec. 2- I have talked to the dealer and customer service person on the phone since day one about the engine making the popping noise aroun 1500 rps to 2500 rpms. I have been told that it will work its way out at the beginning, the boat is to heavy,they have this problem with round bottom hulls and that for some reason the engine doesnt match up with the boat. I have been told this by my dealer, customer service rep and by the evinrude rep for my area. He took the boat out with me and tried to adjust the popping out of the engine and said to just live with it. I know that this is a great engine and the perfect match for tis boat. Thanks Gary

What is the model number on your 90 E-TEC? There are software updates depending on the year that improve runnability and have the capability to calibrate the throttle position sensor for better mid-range running in the 2000 rpm range. That also depends on your top rpm which is governed by your choice of propeller. Give us all the info you can about your rig, model, serial number, mounting height, prop size, rpm, etc. and we'll be glad to help.
