Predictika · Marine transmission orders
An AI sales agent prepares an order for Twin Disc Standard and Quickshift marine transmissions: the model, the duty class of the vessel, the reduction ratio, and the engine that will drive it. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the rating tables in the public Twin Disc Marine Product Guide and returns a verdict, every reason and the figures it computed.
This validator models orders for four Standard and Quickshift marine transmission models in the rating tables of the public Twin Disc Marine Product Guide (November 2025, read October 6, 2026), not just the scenarios shown below.
Any order for these four models that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (the guide lists none, so this validator produces no price build-up or line-item quote), the other Twin Disc models and product lines, the rating tables for the other models in the guide, the electric and hybrid gears, controls, couplings and accessories, ratings at engine speeds the tables do not list, and the torsional compatibility analysis the guide says the system assembler must make.

What this means
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.
| What the validator caught | Typical rules-based CPQ | Predictika |
|---|---|---|
| An engine above the transmission rating | Only with care The rating depends on the model, duty class, ratio and engine speed, so the table has hundreds of cells and every one needs its own rule kept in step with the guide. | The rating is looked up for the exact model, duty class, ratio and speed, and compared with the engine on every call. |
| A ratio the model does not offer | Only with workarounds Each model lists different ratios, and the groups change between duty classes, so a product rule per model and class is needed. | Ratios are listed per model and duty class, and anything else is blocked. |
| Hours and full-power limits of a duty class | Only with workarounds These are limits on how the vessel is used, not on the product, so they need extra rules by class and are easy to leave out. | The duty class limits are checked together with the rating. |
| Ratings given at only three engine speeds | Only with workarounds The guide gives figures at three speeds per class; an engine at any other speed needs a separate rule to flag it. | An engine speed with no published rating is blocked, never guessed. |
| A stated rating that disagrees with the table | Only with workarounds The figure the agent states is free text or a separate field, so it takes an extra rule that compares it with the table. | The stated rating is part of the request and is compared with the table on every call. |
| Every problem returned in one answer | Only with workarounds Rules tend to fire as the order is saved or a step is completed, so a rep often fixes one error and meets the next. | All findings come back together, whatever order the choices arrived in. |
Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.
| 1 | The engine is rated 330 kW but the selected transmission is rated 329 kW at that speed and ratio; the transmission rating must equal or exceed the engine rating. |
| 2 | A reduction ratio of 2.00:1 is not listed in the rating table for the selected model and duty class. |
| 3 | A reduction ratio of 2.43:1 is not listed in the rating table for the selected model and duty class. |
| 4 | The rating table gives no figure at 2,300 rpm for the selected model and duty class; ratings are listed only at three engine speeds. |
| 5 | The rating table gives no figure at 3,300 rpm for the selected model and duty class; ratings are listed only at three engine speeds. |
| 6 | The rating table gives no figure at 3,700 rpm for the selected model and duty class; ratings are listed only at three engine speeds. |
| 7 | The engine runs at 3,700 rpm but the selected model has a maximum speed of 3,600 rpm. |
| 8 | The vessel runs 501 hours a year; the selected duty class allows at most 500 hours a year. |
| 9 | The engine runs 10 percent of its operating time at full rating; the selected duty class allows at most 9 percent. |
| 10 | The vessel runs 1,500 hours a year; the selected duty class allows at most 1,499 hours a year. |
| 11 | The vessel runs 2,001 hours a year; the selected duty class allows at most 2,000 hours a year. |
| 12 | The engine runs 51 percent of its operating time at full rating; the selected duty class allows at most 50 percent. |
| 13 | The vessel runs 4,001 hours a year; the selected duty class allows at most 4,000 hours a year. |
| 14 | The engine runs 81 percent of its operating time at full rating; the selected duty class allows at most 80 percent. |
| 15 | Sportfish charter boats, patrol boats and long range pleasure cruisers do not qualify for pleasure craft ratings. |
| 16 | The quote states a transmission rating of 367 kW, but the rating table lists 329 kW for the selected model, duty class, ratio and speed. |
| 17 | The quote has 0 transmissions; an order needs at least one. |
| 18 | The table ratings are for diesel engines; a person should consult Twin Disc for gasoline engine ratings and required transmission modifications. |
| 19 | Special applications such as dynamic positioning or wind farm service require Twin Disc factory approval. |
| 20 | The engine is rated 350 kW but the selected transmission is rated 329 kW at that speed and ratio; the transmission rating must equal or exceed the engine rating. |
| 21 | The vessel runs 2,500 hours a year; the selected duty class allows at most 2,000 hours a year. |
| 22 | The engine runs 60 percent of its operating time at full rating; the selected duty class allows at most 50 percent. |
