I'm going to build another small tiller-steered skiff this winter, and have been wrestling with which of these engines to power with. I've had a Tohatsu 90 TLDI for the last six seasons on my 20 center console and love it except for one thing: it seems more like a 70hp power-wise. With a...
The factory supplied leads on my motor are about 6' long. For trim purposes on my boat, I extended the leads an additional 15' to the batteries located under the center console. What wire size are the factory leads (they have no identifying AWG number), and must I use the same size AWG for the...
My 2003 90hp TLDI has developed a starting problem recently. I know I need to take it in to my dealer eventually, but I'm not sure there's enough of a symptom yet for him to diagnose. I have a two battery system. The starting battery is a group 27 with an excess of CCA capacity, and the house...
I have a 20' center console powered by a 90hp tohatsu TLDI motor rated for 5150-5850 rpm. With a 13.75x15 Michigan Vortex 3 blade alum prop, she'll hit about 5300 rpm with a light load. For heavier loads, I bought a Turning Point Hustler 14x13 3 blade alum prop. The Hustler will set off the...
I have a 20 center console with a 90hp outboard. running a 13.75x15 Michigan vortex, the motor will spin up to about 5300 rpm with a light load. It's rated for 5150-5850 rpm. I also have a 14x13 alum Turning Point prop for heavy loads that will spin over 5800 rpm lightly loaded. A 14"...
I've been using Pennzoil 100% synthetic tcw3 in my 2003 90hp tldi since day one. Last month I went to the dealer for more oil, and he said to start using the Tohatsu oil reccommended for the motor since the Pennzoil was costing him $25/gallon.
Is it okay to mix the different brands together in...
I have a 2003 Tohatsu 90 TLDI on a 20' skiff. When the boat and motor were new 3 years ago, I went with a 13.75x15 Michigan Vortex alum prop which would get 5700 rpm when lightly loaded. Operating range is 5150-5850 rpm. Now after three years I've added a windshield to my center console, an...
Are you supposed to really tighten the prop nut down hard to try to attain the next hole for the cotter pin to align with, or tighten and then back off to previous hole as you would a wheel bearing? I''ve been trying a few different props, and seem to get more vibration noises at idle in gear...
Trying to get this old motor to run, but no luck so far. I've got spark, but motor won't fire. Took carb apart and cleaned/soaked with cleaner. She's got about 80# compression on each cylinder.
How many turns should I back the slow speed rich/lean needle out of its fully seated position...
internetoutboards only shows 11, 19 and 21 pitch props for a 90tldi. Do you have others not in the e-catalogue? I'm running a 13.75x15 now but can only get 5500 rpms running alone and barely over 5000 with other people or any kind of load. I want to try a 13x13 more or less.<br /><br...
After the winter lay-up, do I need to force feed the engine oil before starting the motor for the first time this year? It's been fogged and stored since last November.
I have a 90hp TLDI on a 20' center console skiff. The prop is a Michigan 13 3/4 diameter by 15 pitch vortex. The hull weighs around 900# without the motor. Total weight with one person aboard is around 1500# including the motor and kicker. When running light like this, the motor will get up...
