    Negative spray on anti-vent plate -

    Vary with trim positions especially when trimmed all the way out....defined as when the RPMs start climbing and the speed starts slowing down? As long as your engine isn't overheating and spray isn't getting in the boat just the price you pay for increased performance....wink!

    Reverse works at low RPM but ‘slips out’ with throttle

    3 possibilities come to mind: 1. Disconnect the shifter cable at the engine/outdrive end with the control box at max R position.....don't let anything move when you make the disconnect that would affect shifting range. Grasp the lever where it was connected to the shift cable and see if it...

    Prop hitting anode

    That's true. I have 2 of those. Certainly the mid range pair vs the high speed pair won't hit the same spot on the TT.....each pair will hit the same spot in different locations. My only alum. props for the last eon were TP aluminum, 3 and 4 blades. I never checked their blade tip...

    Hey Jimmbo, just curious......some names?

    Does my outboard have a thermostat.

    I don't think any of the originally designed, 4 cylinder Mark 30 or Mark55, or the 6 cylinder either up to the Mark 1000 first 100 hp outboard type power heads ever had a thermostat.

    BRP reveals a new style of outboard, Rotax powered, horizontal crankshaft....

    I think they drowned or sank from the stern since the weight and thrust were so far from the stern and slow speeds and cutting the throttle put the powerhead in the water.....just hoping the cowling seals were working. Owners have posted on here concerning my 2 comments.

    Throttle Cable Adjustment 2000 Johnson 90

    On my Mercury 2002 vintage, 90-115 HP, I adjust the barrel on the cable at the engine such that the WOT linkage on the engine stops before the control box can run the cable's length disconnected (at the engine). The barrel is moved forward on the shaft in your case then reinserted in the slot...

    WOT rpm range

    You have your best hole shot with what you have. Obviously running alone, having a rev limiter or you controlling yourself with the throttle will maintain your 6k rated performance. My engines have always run at mid to top end and when I got older and got to boating alone, I always ran the top...

    Prop hitting anode

    If you slide the prop on the shaft and turn till it hits the tab, mark the location the remove the prop, turn it 120 degrees and repeat, then repeat. If all blades don't hit the same point, as others have said, your shaft is bent, the hub is not positioned properly/wrong one/defective, or the...

    What type/size of boat to get for the St. Lawerence river?

    Not being sarcastic but if you can drop 150k on a boat fuel isn't an issue.

    Adding trim tabs, positioning, transducer placement, etc.

    Take your existing transducer and locate a space near the keel (centerline of the hull area) and adjacent to the transom inside the boat. Clean the spot on the hull thoroughly, and rough up the surfaces of that spot on the hull and the bottom of the transducer. Get a JB weld package and weld...

    Power/towing question

    I agree when not under load it can fool you. Possibly some of the winterization material has fouled one or more plugs. Pull them and see if any are wet after running the engine for a few minutes.

    water pump not pumping

    I have always heard that if installed in the reverse direction the blades will correct themselves. In some eccentric pumps I agree. I just redid my 2002 115 Merc and apparently that pump is used on numerous engines above and below that HP and there isn't enough room for the blades to reverse...

    Set up

    If you do try and expect to return, carefully install it, make a test run, if dissatisfied, remove it, clean it up like new and put it in the box. The dealer has to be able to sell it as a new, not used prop if he swaps with you for another.

    No doubt you should hit the sweet spot since you changed 3 things that each are an improvement.

    Battery discharge. ...normal?

    I have a dozen + batteries in equipment plus spares on my farm. Just last month I realized that the normal discharge rate on my batteries, most are new or a year or so old, is much faster than I had anticipated. Makes no difference if the battery is installed in equipment or sitting on the...

    What kind of bolts for aluminum handles?

    Looking at a metals compatibility chart, Aluminum is a Group II metal. Metals in group II are Aluminum alloys, Zinc, Cadmium and Beryllium. With that said, a Cad plated steel screw would be your best bet as long as in the installation you don't disturb the Cad. plating on the bolt......which...

    Prop help, 90hp Merc

    Sorry for the typo....yes its 2.33. Your boat is apples and oranges from mine. You are running a much different rig from mine. I can see where you need to drop pitch significantly to get positive response from that hull/load. You mentioned fuel pump, yes its time for a repair kit as the...
